You can choose between temperature probe or temperature and a humidity probe. The device measures and sends temperature and humidity readings once every 30 minutes. The intervals can be configured remotely via the network. FlexSense uses worldwide Sigfox IoT-network connectivity for data transmissions. 

External temperature and humidity sensors can be freely installed, for example in air duct or different building materials. Sensor cables can also be purchased separately and the central unit is re-usable. 

Versatile, connected, maintenance free, ultra low cost, powerful, accurate - perfect solution for temperature and humidity measurements in demanding environments.
