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 ...

Capacitive sensing is a contactless-sensing technique with numerous applications, ranging from proximity sensing (Fig. 1), gesture recognition, automotive rain sensors, and remote liquid-level sensing ...

Non-contact proximity sensors can improve the ruggedness of manufacturing operations, such as metal component assembly, by replacing delicate mechanical switches. Sensor selection for these ...

Though sometimes dubbed a load-dump sensor, it does not detect dumped loads. The term load dump refers to special circuitry protecting the sensor from high-voltage spikes in the vehicle wiring. The ...
