Capacitive proximity sensor block diagram Capacitive proximity sensors use two metal electrodes or plates to generate a high-frequency electrostatic field.

These sensors have an internal ADC block, therefore they don’t require the end user to design an external block. A microcontroller can directly read the ALS and proximity data using an I 2 C bus.

Elliptic Labs’ AI Virtual Proximity Sensor detects when a user holds their phone up to their ear during a call, allowing the smartphone to turn off its display and disable its screen’s touch ...
