ams OSRAM AG AS8579 automotive-grade capacitive sensor

ams OSRAM's highly accurate capacitive sensors enable reliable and accurate presence sensing of human beings in automotive systems. The AS8579 sensor is capable of detecting the change of capacity in different applications by measuring the relative change of the impedance, which is dependent on the circuit.

Apart from using the AS8579 capacitive sensors for human detection, it can also be used for many other applications, such as Hand-on-Detection for autonomous driving, fluid level sensing, or touchless trunk opening.
