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.

Maxim Integrated introduces it’s new MAXREFDES27# IO-Link subsystem reference design that lets operators tune and calibrate an optical proximity sensor with excellent accuracy, up to 14 bit resolution ...
