Heated Humidity Sensor for Radiosondes

May 29 2017 Comments 0

The HMC03M humidity sensor from E+E Elektronik is dedicated for use in radiosondes and weather balloons. The sensor is characterized by a short response time even at low temperature. An integrated heating resistor ensures an excellent measuring performance under condensation and icing conditions.

The HMC03M combines on a silicon substrate a capacitive relative humidity (RH) sensor and a heating resistor. By heating, the sensor quickly recovers after condensation or icing, which leads to a very good measuring performance even under extreme weather conditions. Another key feature of the HMC03M is the short response time at very low temperature. As a result, the HMC03M is ideal for use in radiosondes to measure humidity in the upper atmosphere.

The very small SMD sensor (5.85 x 2.85mm) is appropriate for automatic assembling with subsequent reflow soldering. HMC03M is available on tape and reel of 500, 1000 or 2500 pcs.

Humidity and temperature probes and transmitters for meteorology

E+E Elektronik’s product range for meteorology also includes probes and transmitters (e.g. EE33-M) for highly accurate humidity and temperature measurement. The sensing elements of these devices are well protected from pollution and corrosion by the proprietary E+E coating. This leads to improved long-term stability and a longer lifetime, two essential criteria for long-term use in weather stations.

From 10–12 October 2017, E+E Elektronik is presenting its sensors and transmitters portfolio for meteorological applications at the Meteorological Technology World Expo (Amsterdam, Netherlands) in Hall 8, Booth 9035.
