2 GENERAL DESCRIPTION

2.1 Basic functionality

The radio transmitter module STM 320 from EnOcean 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. The STM 320 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. A LRN button is pre-installed on the PCB. When this button is pressed a special teach-in signal is sent. There are three frequency variants – STM 320 in 868 MHz, STM 320C in 315 MHz, and STM 320U in 902MHz.

Features with built-in firmware

 Pre-installed solar cell  On-board energy storage and charging circuit  On-board LRN button  On-board TX indicator LED  On-board reed contact

Full performance of the PAS614L energy storage is achieved after several days of operation (up to two weeks) at good illumination level. Performance degrades over life time, especially if energy storage is exposed to higher temperatures. Each 10 K drop in temperature doubles the expected life span.
