Relative Humidity sensors are used to measure the actual humidity condition within the air at any given point or any given place. It measures the Humidity in Percentage (%). Relative Humidity measurements may be used to estimate changes in incident spectrum which may affect PV module power output as well as irradiance sensor readings. Humidity data with temperature data can also be used to calculate the Dew Point. This Relative Humidity Sensor Model is compatible with all Dataloggers, Gateways, and PLCs having Analog input port. It is supplied with mounting facility, and protected from direct sunlight & radiations by a plastic radiation shield.
