Temperature & Humidity Sensor


The Temperature and Humidity (T/H) Sensor is a ZigBee-enabled temperature and humidity sensor. It is makes a great way to measure temperature and humidity in areas of a room that is not near a thermostat. It is also a low cost solution for zoning systems. Embedded with advanced sensing technology, the T/H Sensor is battery operated with a battery life of one year.
