ST’s digital humidity and temperature sensor is based on a planar capacitance technology that integrates the temperature and humidity sensors in the sensing element.
Using our extensive experience in reading small capacitance variations in accelerometers and gyroscopes, ST has developed a differential capacitance sensing element that, when combined with the temperature sensor, provides the relative humidity. It is easy to use with the sensor, signal processing circuitry, onboard calibration and proprietary algorithm integrated in a single package.
The small size and low power consumption is ideal for use cases in consumer mobile, smart home (home appliances and HVAC), and storage and logistic applications.
