Gaia 220 and Type K Thermocouple

Product Description

Gaia 220 is a wireless transmitter for relative humidity and temperature measurements using the CMP5000 probe.

Install the CMP5000, connect it to the Gaia 220 and it will automatically start sending the data continuously. Gaia 220 uses Sigfox, the world’s largest IoT network, which offers a longer range than WiFi or Bluetooth. The data is transmitted to the cloud through nearby Sigfox antennas or gateways.

The humidity and temperature readings are available in the web portal (Sensohive App, Maturix® in Q2 2021). The concrete drying process can be followed in real-time, and you can access the data from anywhere.

The rugged and weather-resistant Gaia 220 is designed to withstand the harsh environment at construction sites. The transmitter can be reused again and again and the CMP5000 probe can be either embedded or installed using a borehole method.


Gaia 220 is available in two variants, one that is certified for use in Sigfox RC1 (20220-1) and one that is certified for use in Sigfox RC2 (20220-2).
