The sensitivity of the proximity sensor circuit can be adjusted with P1 for the desired “distance”. One of its obvious uses is to open a door automatically. For this the sensor must be placed on the ...

Position Sensors play an important role in our daily lives. A position sensor, as the name indicates, provides feedback on the position of the measurand by detecting the presence/absence of an object ...

Two tiny ICs and a few passive components can yield a capacitive proximity sensor with excellent sensitivity and extremely fast response time. The circuit’s operation leverages the pulse-front-edge ...
