In this online engineering specialization, you will master sensor and motor theory and program these devices in a microprocessor system. You will complete courses in sensors and sensor circuit design; ...

The sensor acts as a capacitor (C1) whose value varies from 180 to 220 pF for relative humidity in the range of 0% to 100%. The sensor is linear within ±3% of full scale.

This humidity sensor consists of 2 copper conductors that are located at small distance from each other. The relay switches as soon as the moisture makes a connection that is more or less electrically ...

Next is the humidity sensor circuit. As you know, an easy way to do this is to use a resistive humidity sensor like the HDS-10 dew sensor (see its basic setup diagram below).

Relative humidity, or RH, is the percentage of moisture in the air referenced to the maximum level of moisture the air can hold at that temperature and pressure.

Sensirion has announced a new humidity sensor with a temperature sensor and signal processing circuits on the same chip, a design that shields the device against noise.
