Wireless Temperature and Humidity Sensor


Battery Type: AA

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

Water Resistant

Nodesense digital sensors use digital IC which give accurate and precise temperature/humidity measurements. They can be easily mounted to a surface from where it will start monitoring its surrounding.

The 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.
