EnOcean STM 330U РЧ-модуль

Wireless Temperature Sensor Transmitter Module STM330

The EnOcean STM 330 ISM-band transmitter module incorporates a solar cell power supply and a calibrated temperature sensor. Power is provided by either the on-board solar cell, an external energy harvester or an external 3V battery. An energy storage element is installed to bridge periods with no supply from the energy harvester. The module provides a user configurable cyclic wake up. After wake up a radio telegram will be transmitted in case of a significant change of measured temperature or set point values or if a room occupancy button is pressed. In case of no relevant input change, a redundant retransmission signal is sent after a user-configurable number of wake-ups to announce all current values.

Batteryless Wireless Applications

EnOcean manufacture a range of transmitter and receiver products that operate in the 868MHz area of the ISM band. These devices are typically very efficient in terms of the power supply requirements and are used to send short messages.,The advantages of EnOcean technology are clearly illustrated through applications such as electrical control which eliminates the need for external wired connections and batteries.,Suitable for limitless applications where maintenance free and flexible switching needs to be installed without drilling, cabling and reconstruction costs.,Power in the transmitters is also created for "FREE" using energy harvesting techniques to create energy from the push button switches or solar power for its sensors transmitters.,Radio systems based around EnOcean technology can be formed into star, mesh, or hybrid topology networks, and are a good complement to ZigBee systems, typically in building automation and remote sensor applications.
