Operating principle

The MOZAIC-Humidity Device (MHD) is a special airborne humidity sensing device (AD-FS2), developed by Aerodata (Braunschweig, Germany) and based on the humidity and temperature transmitter HMP230 of Vaisala (Helsinkin, Finnland). The sensing element itself is a combination of a capacitive relative humidity sensor (Humicap-H, Vaisala) and a Pt100 temperature sensor which has been installed in a Rosemount housing mounted on the outside skin of the aircraft in the vicinity of the nose cone.
