Humidity Sensors

We have a complete range of calibrated and amplified products that measure relative humidity (RH).

Based on TE’s robust patented capacitive technology, these sensors provide accurate measurement of dew point and absolute humidity by combining relative humidity and temperature measurements.

Our sensors are qualified for the most demanding applications, including automotive, heavy truck, aerospace, and home appliances.

We offer a variety of output signals such as digital (Frequency, I2C) and analog voltage, as well as, customized and proprietary output signals including PWM, PDM, LIN and CAN.
