Dynalab Relative Humidity Sensor [DWT 8103]

Description

Humidity sensor features an improved design to provide highly accurate and rapid measurements.

PRINCIPLE OF OPERATION: The humidity sensor is a thin film capacitor element. A dielectric polymer absorbs water molecules from the air through a thin metal electrode and this causes a capacitance change proportional to humidity. The response is essentially linear. A sintered filter is provided to protect the sensor element from dirt, atmospheric pollutant and water condensation. A solid-state electronic circuit is built in each probe to produce 0 to 5V output signal corresponding to relative humidity value 0 to 100%. The output is single-ended.
