Perishable goods need accurate and real time monitoring at every step of the distribution and transport chain from producer to consumer. Collecting data during this distribution process is crucial to guarantee the product quality meets the standards set by the producer to ensure the best customer experience. The most obvious application is for the distribution of goods that require to be kept within temperature and humidity thresholds at all times to ensure they do not perish.
IoT technologies can help to monitor such goods along the distribution chain starting at the moment of production, following on during transport and storage. It enables to be alerted in real-time when thresholds are in danger of being exceeded and offer valuable insights to producers and customers report over the distribution chain of a perishable item.
This experiment showcases how temperature & humidity are monitored periodically and send over using LTE-M towards to Maker. When a temperature and/or humidity threshold are exceeded, an asset state will be updated using an automation rule.
Simply hit the upload icon in the Arduino IDE. This will save the sketch, compile it and upload it to your Arduino.
You can now watch the values change in Maker.
Next to that the LED located on the LTE-M RDK board, helps you identify the behaviour of the device.
Alternatively, you can open the Tools > Serial monitor of the Arduino IDE.
Get more insights on how the behaviour of the LTE-M RDK, the modem and/or network by enabling the Debug function in the sketch. This can be done by changing the
false statement to
true in the function
LTEmModem modem, as indicated in the screenshot below.
To visualise our data, we will create a pinboard. For more information on pinboards, please check how to use pinboards.
For extra options to customise your controls, please check the Controls page.
Rules give devices the ability to interact, and create automation. Specifically for this kit and experiment we have created some example rules that can be switched on and adapted to your specific needs:
Time to configure and setup rules! We will activate a provisioned rule.
That’s it! You were notified in the Maker application, by mail and/or push notification on your mobile phone!
For more information on rules, please check how to use rules.
