Wireless room humidity and temperature radio sensor / transmitter KYMASGARD® RFTF2-FSE
The KYMASGARD® RTF 2 - FSE bzw. RFTF 2 - FSE room temperature transducer is a battery-less and maintenance-free radio transmitter. Power is generated by a solar cell that converts indoor room light into electric energy.
The wireless sensor device serves to detect room temperature or room humidity and transmits the measurands via radio frequency to radio actuators and radio signal receivers or gateways. If ambient light conditions are insufficient for power generation, the transmitter can also be operated with a lithium battery cell inserted into a provided holder. The device ID is marked on a label in the housing.
