YO Pure Pro is designed for indoors environmental monitoring. It measures sound pressure level, temperature, humidity, atmospheric pressure, illuminance, CO, CO2, and TVOC concentrations. Sensors measuring CO and CO2 concentrations are pre-calibrated at the production stage. CO and CO2 sensors do not react to other gases in the environment.

YO Pure Pro can be used wherever there is a need to diagnose or improve environmental conditions.

The device communicates wirelessly over LoRaWAN. We are a certified member of the LoRa Alliance, which is responsible for data transmission security.
