Mobile sensor interface for the DGF-I1 gas density sensor

We congratulate Philipp Gurtner on passing his EFZ electronics engineer exam as the best of his year!

TrueDyne: Philipp, what was your thesis (IPA) about?
Philipp: In my IPA I developed a mobile sensor interface for the DGF-I1 gas density sensor. The sensor interface runs the sensor with batteries and reads out the current process values. These are sent via the low-power IoT protocol LoRaWAN. Thus, the sensor interface with sensor can act as a self-sufficient measuring station and wirelessly monitor a plant.

My task was to develop an electronic system that handles the battery management, reads the measurement data, interprets them and sends them to a cloud platform.

TrueDyne: Why did you choose TrueDyne Sensors AG for your training?
Philipp: TrueDyne gave me good support, many possibilities and freedom. The team spirit is very motivating for the daily work.

TrueDyne: What did you enjoy most about your project?
Philipp: The many different tasks in the project brought many exciting things. I found it great to get to know many new things and to work with radio technology.

TrueDyne: What was the biggest challenge in your project?
Philipp: My biggest challenge was the software. I had to go through a steep learning curve in real-time operating systems. This allowed me to learn a lot and it was still a lot of fun when it worked.

TrueDyne: In which direction are your future plans going?
Philipp: At the moment I am looking forward to another great time at TrueDyne with many interesting projects. In the near future I would like to study electrical engineering.
