The project presented here is an analog capacitive proximity sensor. The circuit is from Texas Instruments application note. Most conventional capacitive proximity sensors produce a “1” or “0” output, this circuit produces a DC output that is a function of the size and relative permittivity of an object passing between the sense capacitor plates. Different […]

The circuit published here is an Inductive Proximity Sensor, which is used for non-contact detection of metallic objects. The circuit can be used for the detection of metal objects or as a positioning sensor. The TCA505 is used to design an inductive proximity switch that can detect a metal object from 5-10mm range. The resonant […]
