Real Time Monitoring for the Medical Cannabis Industry

Since being legalised in the UK in 2018, cannabis-derived medicinal products can now be prescribed for a variety of health issues. The term medicinal cannabis refers to the use of the whole, unprocessed cannabis plant or its basic extracts.

How Medical cannabis might be a useful medicine

There are two main parts of the cannabis plant that are of medical interest, they are THC and CBD. THC can increase appetite and reduce nausea, it may also decrease pain, inflammation and swelling; CBD is the oil that may be useful in reducing pain and inflammation and controlling epileptic seizures and possibly some mental illnesses.

How monitoring can help?

Maintaining ideal environmental conditions that support cannabis plant cultivation with good growth and development is not easy to achieve. Glasshouse humidity, temperature, lighting and COlevels are all crucial for the prevention of plant diseases and the promotion of healthy and strong plant growth. Rotronic provide a validated real-time continuous environmental monitoring system that measures all parameters with live alarms using our Rotronic Monitoring system (RMS).

Water Activity

Water activity is the measurement of the available or ‘free’ moisture in a product that can support microbiological growth including yeasts, mildew and bacteria. This affects its stability, quality and shelf life. Most cannabis is dried and cured to a final water activity level of 0.30 – 0.60 Aw. Humidity and water activity influence the quality of the cannabis seeds and dried cannabis products.

The wide range of water activity analysers manufactured and developed by Rotronic are easy to use, convenient and provide fast measurements on-site to confirm product quality.

Rotronic Precise and Reliable Measurement for Weather Stations

casestudy

LSI-Lasten is an Italian company that develops, manufactures and markets a wide range of advanced environmental monitoring systems.  The company was established in 1972 and then began the production of electric thermometers. Later, other parameter devices were added to the product range including relative humidity and air speed utilising the hot-wire method. LSI-Lasten has relied upon the vast sensor technology knowledge of Rotronic over the years and benefits from the use of the outdoor OEM HC2-CP03 cable mount probe in all its sophisticated weather stations. These comprise many different sensors for various parameters, the signals from which are all integrated using data standardisation software. Rotronic meteorological probes measure temperature and relative humidity precisely and reliably. Rotronic offers a wide variety of tailor-made measurement devices which are developed to meet specific customer requirements, for LSI-Lasten the need was for a specified cable length, power supply and outputs with everything designed to fit in a single housing for the installation.

The highest weather station in the world on Mount Everest

By selecting Rotronic sensors, LSI-Lastem was able to ensure not only precise measurement, but also a high level of performance. Mr. Federico Pasquini, chief operating officer at LSI-Lastem, explains:

“The Rotronic probes have completely fulfilled our expectations, because they overcome certain limitations on the measurement of relative humidity in higher regions, even in difficult situations, and this is hard to achieve with other solutions.”

LSI-Lastem specialises in the development and installation of measurement solutions for extreme environments. The company implemented the highest weather station in the world, located on the southern peak of Mount Everest at the amazing height of 8,000 metres. This station includes three Rotronic sensors, demonstrating how the highly developed, reliable technologies by two partners can fully complement each other.

HC2-CP03 Meteorological probe

HC2_S3C_AgroWeissRotronic developed the OEM temperature and humidity cable mount probe for meteorological and outdoor applications. The probe is fitted with a fast response sensor, advanced filter technology that significantly improves protection of the humidity sensor against the formation of biofilm, and an increased power supply range suitable for battery operated systems.

Air Humidity and Temperature Under Control

The Laténium in Neuchâtel is the largest archaeological museum in Switzerland, with more than half a million artefacts. The most common problem for the museum in storing the ancient relics, is the variation in air humidity and temperature. There is no air conditioning system in the building, the museum uses temperature and humidity measurement probes to monitor the environment. The Laténium Museum has two laboratories, one where wooden artefacts are dated and which provides highly specialised services, and a laboratory for conservation and restoration work. Rotronic probes are used due to their high precision and advanced functions, they control the environments in glass display cabinets, exhibition rooms and storage areas. The museum houses 524,450 objects dating from the Neanderthal era through to the renaissance. Around 70 Rotronic temperature and humidity probes are installed.

Preserving the Artefacts

1510316889_keller_rke-RK5_5880Finding an archaeological object is of course of great importance. It is first removed from its surroundings and then kept under suitable conditions. During this time, it is expected that the object will start to destruct, the climate plays a huge part in this.  If artefacts are not stored under the right conditions, their condition can deteriorate very quickly; air relative humidity of about 50 % is ideal.

Continuous monitoring system

Thanks to the Rotronic Monitoring system (RMS) the Laténium Museum has a complete overview of the probe installation locations with optimal environmental control. RMS provides a complete, flexible and yet easy to use continuous environmental monitoring solution instead of multiple fragmented and complex systems working in isolation. The RMS software stores all recorded measurements securely in a system that the user can access at any time, data can be retrieved in any form and integrated into third party systems, automated reports are easily generated and sent autonomously to key personnel. The heart of the system is server-based web software with a secure SQL database. It records all data and events generating a range of alerts or warnings when the museum’s defined criteria are breached. The RMS data loggers transmit the measured values to the software via wireless or LAN communication.

The Benefits of Using Rotronic Precision Temperature and Humidity Probes

Organic materials are sensitive to the climate, they will deteriorate following any variations. Artefacts are stabilised at a relative air humidity of 50 %. As the museum is not air conditioned, the curators decided to install climatic controls in every glass cabinet that housed archaeological objects to ensure they were kept at a constant humidity level. Each cabinet has a cartridge fitted containing buffer material. Using the Rotronic RMS software, the museum can control the cabinets from a computer screen. It can provide detailed charts for a year, a week, a day or an hour to suit the application being monitored. These charts allow the curator to track seasonal or weekly fluctuations in humidity and temperature and will identify any anomalies.

The Laténium Museum opted for the Rotronic system because it can achieve high precision in humidity measurement of ± 0.8 %rh while other manufacturers could only offer ±2 %rh.

Scientific projects at the Laténium

The Laténium Laboratory for Conservation and Restoration is involved in various scientific projects in fundamental research as well as applied research (including the development of marketable products). This work is conducted in partnership with the scientific institutes of various colleges and universities in Switzerland as well as other organisations.

Rotronic Monitoring System integration. Pulling data into your systems

Data Integration is Key

Data integration is one of the primary requirements for many of our customers. I have previously discussed how RMS easily supports the integration of external data, but this posts takes a look at how RMS allows you the export data.

https___www.rotronic.com_media_events_images_1495454818_RMS_ML_GW

Of course RMS provides excellent graphing, statics and reporting as part of its core functionality, however here we are discussing the tools that will more likely be used for Machine to Machine (M2M) integration.

m2m

Machine to Machine (M2M) integration is absolutely key as data is increasingly being used for different purposes through businesses. So whilst RMS provides a highly secure and configurable platform for monitoring and alarming there are many weird and wonderful functions that it cannot provide. In this case we need to pull the data out and use it elsewhere.

Getting Data out of RMS

RMS is an SQL based system so we could of course query the SQL directly however there are many limitations with this approach especially security. Also via our RMS cloud platform absolutely no direct SQL access is available to end users.

Instead RMS supports a RESTful API, we’ll use a simple example to go through the basic steps.

RMS GET API

As before I’ll use some Python scripts in this example but if you prefer, POSTMAN is a great tool for testing these types of APIs.

Let’s breakdown the steps.

  1. Request API token using your username and password
  2. Use Token to request specific data
  3. Use data as required

Step 1 – Request a Token.

For security reasons you cannot simply send a request and get whatever data you desire. First you must request a token from RMS. The token is linked to a user account and will only allow the data that is visible by that user to be accessed. When requesting a token you can also specify how long it is valid for. The maximum length is 30 days.

import json
import requests

url = ‘https://rms.rotronic.com/RMS/API/RequestToken.ashx’
headers = {‘Content-Type’ : ‘Application/json’, ‘Expect’ : ‘100-continue’, ‘Connnection’ : ‘Close’, ‘Host’ : ‘rms.rotronic.com’}

UsrID = “1”
User= “Jeremy”
PW = “########”
Exp = “30”

get_payload = {‘UserId’:UsrID,’Username’:User,’Password’:PW,’RequestType’:’ DataHistory’,’ExpirationDays’: Exp}
api_get = requests.post(url, headers=headers, data =json.dumps (get_payload))
token = json.loads(api_get.content)
token = token.get(‘Token’)

The above request with suitable credentials will return something along these lines.

{‘UserId’: 1, ‘RequestType’: ‘DataHistory’, ‘Token’: ‘jUsTaNeXaMpLe_HRwOi8vd3d3LnczLm9yZy8yMDAxLzA0L3htbGRzaWctbW9yZSNobWFjLXNoYTI1NiIsInR5cCI6IkpXVCJ9.eyJVc2VySWQiOjM5MzEsIlJlcXVlc3RUeXBlIjoiRGF0YUhpc3RvcnkiLCJFeHBpcmF0aW9uIjoiMjAxOS0wNC0wM1QxNToyMzoyMC44MTgwODM4WiJ9.rtHHKvrE-7jnMNHUGazso_jUsTaNeXaMpLe’, ‘Status’: ‘OK’}

The API token being the jumble of text above. With the token in hand we can proceed with requesting our data.

Step 2 – Request Data

To request data we need the measuring point ID for the data we need which can be obtained from the RMS interface (every measured parameter has a unique ID within RMS that will not change and cannot be reused). We also define the From and To ranges as well as the number of values we wish to obtain (Count).

import json
import requests

url = ‘https://rms.rotronic.com/RMS/API/DataHistory.ashx’
headers = {‘Content-Type’ : ‘Application/json’, ‘Expect’ : ‘100-continue’, ‘Connnection’ : ‘Close’, ‘Host’ : ‘rms.rotronic.com’}

MPTID = “20”
From = “2019-03-04T08:00:00”
To = “2019-03-04T09:00:00”
Count = “10”
Token = “token from step 1”

post_payload = {‘ID’: MPTID,’From’: From,’To’:To,’Count’:Count,’Order’:’Asc’,’Token’: Token}
api_get = requests.post(url, headers=headers, data =json.dumps (post_payload))
data = json.loads(api_get.content)
print (data)

The above request with suitable details will return something along these lines.

{‘Status’: ‘OK’, ‘ID’: 20, ‘Name’: ‘Humidity-18071604′, ‘Parameter’: ‘Humidity‘, ‘Unit’: ‘%rh‘, ‘Data’: [{‘Time’: ‘2019-03-04T08:00:14+01:00′, ‘Value’: ‘29.45%rh‘}, {‘Time’: ‘2019-03-04T08:05:14+01:00’, ‘Value’: ‘29.80%rh’}, {‘Time’: ‘2019-03-04T08:10:14+01:00’, ‘Value’: ‘29.61%rh’}, {‘Time’: ‘2019-03-04T08:15:14+01:00’, ‘Value’: ‘29.29%rh’}, {‘Time’: ‘2019-03-04T08:20:14+01:00’, ‘Value’: ‘29.80%rh’}]}

Step 3 – Use the data

So we have our data in JSON format from here it’s an easy step to chopping out the specific values and handing them over to some other code, machine or simply displaying them for yourself.

The flexibility of RMS is an important requirement for our customers especially those with existing systems. Using RMS as the central platform ensures precision measurements, secure and reliable data collection and easy access to data. Using our  APIs then allows this data to be utilised in wider business operations.

integration examples

Customer examples using the API include

  • Live temperature data included in packaging labels
  • Automated calibration certificate generation using reference values from RMS
  • Visualisation of RMS data on 3rd party software for building efficiency displays

Conclusion

This article focuses on our RESTful API however we have many other options for integration of data including relay output modules, analogue output modules, direct SQL connection. In addition our RMS-Integrator hardware offers direct communication with devices via MODBUS, SNMP and MySQL.

So the message is simple; if you have requirements RMS can usually deliver what you need. Please contact us and we will be happy to discuss your project be it large or small.

Temperature Mapping & GDP-Compliant Warehouse Qualification

casestudy

At the World Cargo Centre (WCC) Leipzig/Halle airport a cold store for air freight shipments was built for aircraft loads of temperature-sensitive goods to enable them to be stored at correct temperatures.

The cold store, operated by PortGround, can store goods at temperatures of +2°C to +25°C. Rotronic carried out a winter mapping assessment of the climate conditions. To ensure that customer requirements of PortGround GmbH were met.

Before mapping can take place in any warehouse or other storage facility, you must ensure you  identify the risk areas that could cause deviations in temperature and humidity leading to potential product quality problems.

General procedure
The control and fluidity of storage spaces are influenced by a number of factors. Once the risk areas have been identified, before mapping takes place a test must be developed, providing the following Information and the basis for each decision:

• Types of data to be generated – e.g. temperature, relative humidity and their measurement intervals
• Number of sensors required
• Deciding the positioning of the sensors
• Duration of the investigation
• Summer and winter mapping
• Requirements for calibration of the data loggers
• Acceptable limit values for temperature and relative humidity
• Report generation requirements

The data loggers are then positioned in the warehouse according to the model. Additional data loggers are then used in the identified risk areas where draughts from loading ramps, heat or cold radiation from external walls, solar heating through windows, heating by lamps, air circulation from traffic or the HVAC system could occur. Many factors can impact temperature and humidity conditions which is why the initial risk assessment of the specific site is critical.

Rotronic offers several solutions for thermal mapping, including stand alone data loggers and wireless data loggers. Stand alone data loggers are batch configured and data is batch downloaded for analysis and reporting via our HW4 software. Wireless loggers connect to our RMS platform and can provide live data during the mapping or alternatively where live connection is not possible or required data is automatically downloaded once loggers are back in range of a suitable gateway, via RMS data can be automatically analysed for deviations. For example our engineers can park at the office car park and all the devices automatically reconnect, download and deviation reports are generated without a single click of a button.

Based on the project master plan final reports will be generated with deviations listed. The basic information shown is listed below:

• Data with time and date
• Calculated values such as average, standard deviation, temperature minimum, temperature maximum, MKT.
• Deviation details and summary
• The characteristic of all data loggers over the test period
• The device settings
• Date and time of the test
• The calibration information

The position of individual sensors can be displayed in a graph to provide a quick overview of possible extremes in temperature and relative humidity. The outside temperature and humidity can also be recorded. Then, for example, a temperature peak can be associated with a time when the gates of the loading ramp were open.

hl-1d1HygroLog HL-1D is suitable for monitoring and recording conditions for  a wide range of applications across all industries, in commerce and for research organisations.

The compact logger is particularly suitable for monitoring high value products of all types during transportation to ensure that quality is maintained.

Simple USB interface and low cost makes these devices ideal for thermal mapping projects.

https___www.rotronic.com_media_events_images_1495454818_RMS_ML_GW

RMS-LOG and RMS-MLOG devices offer benefits of live data allowing monitoring of the mapping data ensuring devices are operating normally.  Automated download and reporting is a luxury but for large projects this can save significant time. The RMS-LOG provides accuracy of 0.8%rh and 0.1°C and with interchangeable probes calibration costs can be reduced.

Contact us to discuss thermal mapping services or products so you can undertake or thermal mapping yourself.

Monitoring Medicines

casestudy

Medicines are sensitive products. High or low storage temperatures can impair their quality. Incorrectly stored medicines lose their efficiency and can be harmful to health. Therefore correct storage is vital to ensure that medicines remain safe, efficacious and retain their high quality right up to their stated expiry dates. The Rosengarten Apotheke Pharmacy in Bassersdorf, Switzerland relies on the Rotronic Monitoring System to record temperature conditions during medicine and chemical storage, with full alarms.

GDP/GMP requirements in pharmacies
The storage of medicines is legally regulated by GDP Standard 9.2. Temperature sensitive pharmaceuticals such as insulin, liquid antibiotics and certain eye drops, must be stored in medicine refrigerators between 2 °C and 8 °C. A temperature range of 15 °C to 25 °C applies to the vast majority of other medicines. It is compulsory to document the actual storage conditions of all medicines. The Rosengarten Apotheke Pharmacy previously recorded temperature values by hand. The Rotronic Monitoring System (RMS) now eliminates this work. The RMS loggers transmit their measured values to the ISO 27001-certified RMS Data Centre via a gateway in real time; it stores the data centrally and securely. Access to all the data is available anywhere, on any device via a secure internet address. Measurement devices also log several weeks of data providing a secure backup in the event of any communication or power interruption to the facility.

RMS-overzichtCarefree package
The  Rosengarten Apotheke Pharmacy opted for an RMS leasing contract which includes the use of hardware and cloud-based software and support all under one fixed price Service Agreement. With this convenient solution Rosengarten Apotheke Pharmacy did not have to purchase any equipment or set up its own IT infrastructure and benefits from the full service package. This includes annual sensor calibration, battery replacement and direct support as needed. During the consultation meetings with the customer, we defined and proposed the monitoring system as required to meet the legal requirements. After approval, the required hardware was calibrated, installed and configured by Rotronic personnel on site.

Alarms
As soon as a measured temperature value falls below or exceeds the defined limits, the system triggers an alarm; an email is then sent to the designated person. Four alarm levels can be selected in RMS, depending on the risk, ‘Reminders’ for non-urgent events, ‘Warnings’ or ‘Alarms’ for measured values outside set limits and ‘Errors’ for possible hardware errors. Notified alarms must be acknowledged; causes and corrective measures can be entered and stored for audit and route cause analysis purposes.

For more information on the Rotronic Monitoring System (RMS) or our Solution as a Service models please contact us or visit our website www.rotronic.co.uk

The Rosengarten Apotheke Pharmacy has been deeply rooted in the community of Bassersdorf Switzerland, since 1960.

Monitored areas:
• Sales and storage rooms
• Picking machines
• Refrigerators for medicines and chemicals
