Battery Powered Sensors (EDs)


Sensor nodes are used in conjunction with the Sontay RF-RX20, RF-RX40 or RF-RXS receiver units, and if required (depending on installation topography), Sontay RF-RR series of routers.

Data is transmitted back to the receiver at configurable time intervals, or on a configurable change in measured value. Each sensor retains these configurations if the battery becomes discharged or requires replacement. The sensors automatically find the best path back to the receiver, which may be directly to the receiver or via ‘parent’ routers.



Radio Output:2.4 GHz frequency, 16 channels
Accuracy: Temperature ± 0.3°C
Relative Humidity ± 3%
Battery Life: > 3 years (depending on configuration)
