STM 350U – Batteryless and Wireless Temperature & Humidity Sensor Module

The extremely power saving RF transmitter module STM 350 of EnOcean is optimized for realization of wireless and maintenance free temperature and humidity sensors or room operating panels including set point dial and occupancy button using the EnOcean radio standard.

It requires no external components and provides onboard a calibrated temperature and humidity sensor. Power supply is provided by a small pre-installed solar cell or an external 3 V backup battery. An energy storage element is installed in order to bridge periods with no supply from the energy harvester.
