Buy humidity sensor (capacitive) from Vishay - a humidity sensor which operates on a capacitance charge with change in relative humidity.
Incorporates The following features: 10 to 90%RH humidity, 122pF capacitance, 0.4pF/%RH sensitivity, 3% hysteresis, 300s response time, 0°C to 85°C, 1 to 1000kHz frequency, 15V supply voltage, this capacitive atmospheric humidity sensor consists of a non-conductive foil, which is covered on both sides with a layer of gold, the capacitance value of the sensor is a measure for relative Humidity.
