DATA SHEET - Sensors

This sensor sheet includes the most common sensors. A Sensor Interface Module is also available.

HUMIDITY SENSOR: The MiniCap2 humidity sensor is manufactured using state-of-the-art semiconductor technology. The dielectric constant of the thin film polymer changes with atmospheric relative humidity, resulting in a linear capacitance change. The MiniCap2 is unaffected by water condensation and is immune to most reagent vapors.
