CLIM'O compact LoRaWAN® Temperature and Humidity sensor for indoor air monitoring

The sensor measures the temperature and relative humidity inside. Data transmission over a public or private LoRaWAN® network is carried out periodically or immediately in the event of
alarm case: 

• minimum and maximum temperature thresholds exceeded
• minimum and maximum humidity thresholds exceeded,

Installation and commissioning are quick and easy. The sensor is equipped with:

• a magnetic switch for activation and deactivation,
• LEDs to monitor configuration and coupling to the network.

Each sensor is identified by a QR code on the label. Measurement data are transmitted individually or aggregated and compressed (batch mode) before being transmitted over the LoRaWAN® network. Batch mode significantly reduces the amount of data transmitted, preserving sensor autonomy. Powered by a 3.6 V/2600 mAh battery, the sensor autonomy is over 8 years  with a configuration of 1 measurement every 10 minutes and 1 transmission per hour. The battery voltage level can be regularly monitored remotely.
