The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

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 ...

It depends on the IR emitter intensity and pulse to detect the proximity. Figure 1 shows a typical ALS/Prox sensor block diagram. 1. This block diagram represents a typical ALS/Prox sensor.

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors.

AI Virtual Proximity Sensor INNER BEAUTY Elliptic Labs’ AI Virtual Proximity Sensor detects when a user holds their phone up to their ear during a call, allowing the smartphone to turn off its ...
