The ChipCap 2 is a capacitive polymer sensor chip and a CMOS integrated circuit with EEPROM integrated into one embedded system in a reflow solderable SMD package. Individually calibrated and tested, ChipCap 2 performs at ±2% from 20% to 80% RH (±3% over entire humidity range) and is simple and ready to use without further calibration or temperature compensation. ChipCap 2 provides linear output signals in I²C interface and is PDM convertible to analog signal with an alarm function for preset control at min/max humidity, based on customer requirements.
