AS8579 Sensor Interface
Infineon Technologies AS8579 Sensor Interface detects capacity changes in different applications and measures the relative change in impedance, depending on the circuit. The sensor is used for human detection and many other applications. The Infineon Technologies AS8579 measures the current from a metal object and applies algorithms to determine its capacitive and resistive properties (impedance). This information can be read via an SPI interface that can also be used for IC configuration.
