Measuring Humidity using HSM 20G

Humidity sensor is a device consisting of a special plastic material whose electrical characteristics change according to the amount of humidity in the air. Basically it is a sensor that senses the amount of water vapor in air. The module of HSM-20G is essential for those applications where the relative humidity can be converted
to standard voltage output. The humidity sensor module HSM-20G is shown in figure below.
