Relative Humidity Sensor With Modbus Output
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 (%). This sensor measures also the Ambient Temperature where the PVs are placed in degrees Celsius (°C). 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 ambient temperature data can also be used to calculate the Dew Point. This Relative Humidity Sensor Model is compatible with with all Dataloggers supporting Modbus RTU Protocol. It is supplied with mounting facility, and protected from direct sunlight & radiations by a plastic radiation shield.
