Very Fast Humidity Sensor for Radiosondes
HC103M2
HC103M2 is a capacitive humidity sensor with very short response time even at very low temperature. By this, the sensor is ideal for accurate measurement in the upper atmosphere with radiosondes and weather balloons.
HC103M2 humidity sensor
The sensor is manufactured in state of the art thin film technology and is appropriate for SMD assembling. The design and the choice of materials leads to excellent linearity, high sensitivity and reproducible temperature dependence, which facilitate considerably the design in.
HC103M2 is supplied on tape and reel appropriate for standard SMD assembly machines.
