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 ...

Here is the diagram of my Arduino infrared close proximity sensor. As you can see, ... Apart from the Arduino UNO, the circuit consists of two more primal parts – an infrared emitter and an infrared ...

IR Sensor Pinout. The IR sensor has a 3-pin connector that interfaces it to the outside world. The connections are as follows: VCC is the power supply pin for the IR sensor which we connect to the 5V ...
