RFTF2-FSE radio room humidity and temperature sensor with solar cell and 2 channels FRIJA II

The room temperature sensor KYMASGARD~ RTF 2 - FSE respectively humidity sensor RFTF 2 - FSE is a battery-free and maintenance-free radio transmitter. Energy is generated by converting ambient light into electrical energy by means of a solar generator. This sensor serves to measure room temperature and humidity, respectively, and sends its values radiographically to radio actuators and receivers/gateways. If there is insufficient ambient light, the sensor can be equipped with a lithium button cell. This can be inserted into the holder provided for this purpose.
