      HMC03M Heated Humidity Sensor for Radiosondes and Weather Balloons

      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.

      Features:

      Very short RH response time at low T
      High sensitivity
      Fast recovery after condensation or icing due to sensor heating
      High accuracy thanks to outstanding T uniformity within HMC03M
