ENOCEAN STM 330 Wireless Temperature Sensor Module, 868MHz

The ENOCEAN STM 330 is an extremely power-saving RF transmitter module, specifically engineered for creating wireless, maintenance-free temperature sensors and room operating panels. Its optimised design requires a minimal number of external components, simplifying integration for systems that include a set point dial and occupancy button.

At its core, the module features an integrated, factory-calibrated temperature sensor, ensuring reliable and accurate readings without the need for additional calibration. For enhanced environmental monitoring, it also supports the plug-in HSM 100 humidity sensor module, allowing for a comprehensive climate sensing solution.

Harnessing advanced energy harvesting technology, the module is equipped with a pre-installed solar cell, enabling it to operate entirely without batteries or wired power sources. This makes it ideal for installations where long-term, maintenance-free operation is critical. Communication is robust and efficient, utilising a 868.3 MHz frequency with ASK (Amplitude Shift Keying) modulation at a data rate of 125 kbps, supported by a pre-installed whip antenna for reliable signal transmission.

With its compact dimensions and ultra-low power consumption, the STM 330 module is a cornerstone technology for smart, sustainable building and industrial systems, providing precise data where and when it is needed.
