ChipSensors produces innovative single-chip CMOS sensors. Our product roadmap includes digital sensors for temperature and humidity, as well as specific gases and pathogens.

CS114 - Relative Humidity and Temperature Sensor in a 4x4 QFN Package

Description

The CS114 integrates temperature and humidity sensor elements, an analog-to-digital converter, signal processing, calibration data, and an I²C interface all in a 4x4mm QFN package. Each CS114 is individually factory calibrated for both temperature and humidity with calibration data stored in on-chip non-volatile memory. This ensures that the sensor is fully interchangeable, without any recalibration or changes to software.

Patent-pending use of industry-standard-CMOS low-K dielectrics enables the CS114 to achieve long term stability, low drift and very high immunity to contaminants.
