The primary working principle behind the PCF8885TS/1,118 interface sensor is capacitive touch sensing. This technology uses a substrate of conducting materials to create a ‘sense field’ which can respond to the presence of nearby conductive material, such as a finger. When a finger is placed within the sense field, it causes the capacitance to change, which is detected by the sensor. Based on the change in capacitance, the sensor can then determine the position of the finger on the sensing area and send a signal to the host processor.

In addition to providing a precise way to detect the presence of a finger, the PCF8885TS/1,118 interface sensor also features a number of other features which make it an ideal solution for applications requiring precise touch sensing. These features include:

• High immunity to electromagnetic interference
