Working principle of HPP845E034R5

The working principle of HPP845E034R5 is based on the capacitive humidity measurement technique. The relative humidity sensor contains two parallel plates and a sensitive material between them. As humidity is present in the air, the polymer film absorbs moisture and the two plates capacitance will increase. By measuring the capacitance of the humidity sensor, the changes in relative humidity can be determined.The capacitance of the HPP845E034R5 humidity sensor is measured by an on-chip Circulating ROM frequency measurement circuit. The humidity data is converted into a 16-bit digital output, which is then transmitted to the external microcontroller or data logger via a two-wire bus. This operation is based on the humidity and temperature combined signal processing technique and is power efficient.
