Covid-19 vaccine temperature monitoring by transmitting
measurement data using LoRa and LoRaWAN technology

Thesis abstract:

The project goal was to develop a system for monitoring Covid-19 vaccine temperatures during storage using LoRa and LoRaWAN technology. The project based its temperature range criteria on Pfizer’s vaccine. The monitoring of these temperatures is important to make sure the Covid-19 vaccine keeps its life expectancy before the next step in the vaccine process.

To solve this task a LoRaWAN system with an end device for temperature measurements was implemented. The end device transmits its data to a back-end system for data storage, data visualisation, and user notification when temperatures reach crucial levels.

Measuring ultra-low temperatures was done successfully by using a K-type thermocouple. These measurements are successfully transmitted to the back-end system. The measurements were visualised in a way that suits the measurement type, and the user was successfully notified by SMS and email when the temperature reached a crucial level.

The project did not have a pre-study form, but topics that needed study became clear as the project progressed. For development, the project team used the rapid prototyping approach.
