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 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 various
interfaces to customer requirements:
•
•
•
I²C interface
PDM convertible to analog signal
Alarm function for preset control at min/max
