- Operating Humidity range: 0to100%RH
Description:
The capacitive humidity sensor of Smartec is based on silicon technology on glass water. Due to the use of this process it is possible to make sensors on a high volume scale on a low cost way. The Smartec humidity sensor consists of three layers. The base and top layer are conductive and the layer in between is humidity sensitive polyimide. The selection of this sensitive interface makes the sensor highly independent to temperature effects. The top layer has grid like structure. The sensor converts the humidity in to a capacitance. Due to the construction the response to humidity is very fast (<15 sec) and the hysteresis very low (<2% RH.)
