Air Temperature and Humidity Sensor

The Sourayan Make Ambient Temperature and Relative Humidity Sensor is a low cost, highly accurate and precise sensor. The sensor is mounted inside a naturally ventilated multi-plate radiation shield for precise measurement. The radiation shield protects the sensor from direct exposure to weather conditions and at the same time protects it from dust. The sensor can be easily mounted on a pole or tripod. It has no moving parts, thus offering a maintenance free operation.
