Radio sensor powered by a mini solar cell—the EnOcean STM 110 now functions with even less light
In this paper, EnOcean presents their radio sensor module STM 110 in more detail. The module obtains its operating energy from a small solar cell. Like its predecessor, the STM 100, the STM 110 sensor module was designed as a maintenance-free radio module to transmit various sensor information. It can be powered by the solar cell that comes with it and which measures just 13mm x 35mm. An integrated energy store enables the module to function fully, even after several days of total darkness.
