STM320U

STM320U is an energy harvesting magnet contact transmitter module that enables the implementation of a wireless magnet contact sensor. Powered by a solar cell, it works absolutely maintenance-free. An integrated energy store allows operation for several days even in total darkness. Key applications are window and door sensors. It supervises an integrated reed contact and reports every status change immediately (open<>closed). In addition a sign of life signal is transmitted every 20-30 minutes. In enhanced secure mode the communication is protected by encryption.
