Relative Humidity

Humidity in rooms, storage areas and laboratories can be followed with wireless humidity and temperature sensors, including sealed versions, long-range wireless transmitters and monitors that add CO2 and atmospheric pressure. For standalone recording, there are compact humidity and temperature loggers and cloud-connected loggers.

Transducers with 0-10 V or 4-20 mA outputs, which also report dew point, bring humidity readings into loggers, and large LED displays show the value in the room itself.
