I was part of a team of four that developed moduLo.

We built a sensor module that uses the Helium Network to measure Temperature, Humidity, eCO2 and Hydrogen Levels in the air.

We designed and 3D printed a case, which contains a custom PCB. It uses an ESP32, RFM9X radio, DHT11 Sensor, SGP30 Sensor along with various other components for power management and I/O. We power it off 4xAA batteries, and it'll last just over 12 days.
