HMC03M Heated Humidity Sensor Description
HMC03M is optimized for short RH response time even at very low temperature in the upper atmosphere. It combines on a silicon substrate a capacitive relative humidity (RH) sensor and a heating resistor (heater).

The heater is dedicated for fast recovery of the humidity sensor after condensation or icing. The construction with the heater positioned all around the RH sensor grants uniform temperature throughout the HMC03M structure, which leads to outstanding measuring performance in high-end weather observation.

HMC03M Heated Humidity Sensor Features
* Very short RH response time at low T
* High sensitivity
* Fast recovery after condensation or icing due to sensor heating
