ChipCap2 Humidity / Temperature Sensors


Amphenol Advanced Sensors introduces an advanced and cost-effective humidity and temperature sensor


Amphenol Advanced Sensors' ChipCap2 offers the most advanced and cost-effective humidity and temperature sensing solution, ideal 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, ChipCap2 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.
