Wireless Temperature Sensor

Wireless Temperature Sensor


Battery Type: AA

Frequency: 867MHz(India)/868MHz(EU)/915MHz(U.S.)

Water Resistant

The wireless NTC based thermistor measures temperature in the range of -55 °C to +125 °C. The sensor is programmed to sleep for a given time interval, wakeup and transmit the recorded temperature to the gateway. The standard version of this sensor is powered by two replaceable 1.5V AA batteries.
It is also available with direct DC power supply option. This version of the device has a DC jack opening where a 5V supply can be provided via an adapter.
