Relative Humidity Sensor

Relative Humidity Sensor
The Relative Humidity sensor BT72i measures
relative humidity. The sensor consists of an
integrated circuit, which uses a capacitive
polymer to sense humidity. The holes in the
sensor box provide air circulation.
Range: 0 to 100 %
Resolution (12-bit): 0.04 % RH
Can be used to:
? study transpiration rates of plants,
? optimize conditions in a greenhouse
or terrarium,
? determine good days for static electric
demonstration.
