Product Overview
The ChipCap 2 is a fully-calibrated and temperature-compensated humidity and temperature sensor designed for a wide range of applications. It offers precision and accuracy with digital or analog output options and an alarm function. This sensor is ideal for energy-saving HVAC control, process control and instrumentation, automotive and transportation systems, and medical devices. Its compact SMD package allows for automated assembly and reliable performance in harsh environments. The ChipCap 2 integrates a capacitive polymer sensor chip and CMOS integrated circuit with EEPROM into a single, reflow solderable unit, providing a cost-effective and advanced sensing solution ready for use without further calibration or temperature compensation.
