ChipCap® 2 offers the most advanced and cost
effective humidity and temperature sensing
solution for virtually any type of application.
A capacitive polymer sensor chip and a CMOS
integrated circuit with EEPROM are integrated
intooneembeddedsysteminareow
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
various interfaces to customer requirements:
• I²C interface
• PDM convertible to analog signal
• Alarm function for preset control at min/
max humidity
