GreenWake Technologies RF energy harvesting technology provides high efficiency solutions for wireless powering of energy autonomous sensors


GreenWake Technologies offers fully operational devices for wireless, battery-free sensor operations. Our off-the-shelf product range is ready for deployment and currently includes PWT-04 power transmitters, DTR-868 data transceivers and AST autonomous sensor tags. It covers a wide spectrum of industrial applications.

Data transceiver DTR-868

The DTR-868 data transceiver enables bi-directional data communication with AST sensor tags as well as one or more DTR-868 transceivers using an 868 MHz carrier wave. The DTR-868 transceiver comes with embedded web server and control software permitting identification of sensors, setting-up interrogation modes and sending commands to the sensors.
