The 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 ... 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.
