WNS (ZigBee Wireless Sensor)

The WNS-TxxxB are battery powered wireless temperature and humidity sensors with setpoint adjustment and override push-button that transmits sensor data through a enteliMESH wireless network. Each battery powered sensor incorporates a low power radio which meets standards for operating within the ISM 2.4 GHz frequency band. The battery provides up to 5 years of service before replacement.


Typical applications include mounting in specialized areas that are difficult to wire, such as on solid concrete and marble walls or in atrium, foyers, auditoriums and architecturally sensitive installations. Other applications include the use in spaces that change periodically such as tenant retrofit areas or areas that require monitoring, such as data centers.

The WNS-TxxxB has an optional pushbutton and setpoint adjustment. An extra set of terminals allows for remote location of an external thermistor temperature probe which can be used to retrieve temperatures from inside a cold storage box, environmental chamber or from an outside location.
