EnOcean released a Developer’s Platform that enables OEMs to design self-powered wireless sensors that do not require batteries or external power. The EVA 120C Evaluation Kit includes everything necessary to quickly develop and test ultra low power wireless sensor modules for a variety of electrical and electronics applications.
Kit components include an EnOcean STM 110C solar powered sensor transmitter module and a development board with a PC interface. Detailed technical documentation, including data sheet, manual and user notes also are part of the kit.
The STM module is the only commercialized product that integrates a wireless sensor, low power radio, solar cell power generator, microcontroller and ultra low power sleep timer and threshold detector for energy management. All module elements have been optimized to work together.
