DigiPicco™ Basic I2C

Capacitive Humidity Module

Digital (I

Within the markets Measurement, HVAC, Building and Control, and Home Appliances/White Goods, humidity

modules are required which are capable to translate the signals of the robust IST humidity sensors into commonly

used standards and provide a calibrated sensor signal. Contrary to existing humidity modules or fully integrated

solutions the DigiPicco series unifies advantages of both worlds, avoiding their disadvantages: The high precision

measurement of humidity with discrete sensors (high stability due to wide active sensor area) combined with

calibrated and linearized output signal and fully digital output of both humidity and temperature.
