Presence, Proximity Sensor Circuit Schematic proximity sensor circuit schematic The sensitivity of the proximity sensor circuit can be adjusted with P1 for the desired “distance”. One of its obvious ...

Here is the reference circuit diagram of a simple inductive proximity sensor, wired around the 8-pin proximity detector chip TDA0161. This monolithic integrated circuit (from STMicroelectronics) is ...

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 ...
