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 ...

The sensor shown here is essentially two plates mounted side-by-side, attached to an Arduino Nano using the Capacitor library which uses just two pins, one digital and one analog.

A proximity sensor detects the ball and starts up a pair of 540 R/C motors, ... Posted in Tool Hacks Tagged arduino, proximity sensor, router, VCNL4020, woodworking. Gesture Based Security Lock.

This project is a simple modification of the LightGauge project. Instead of measuring light, we measure the ambient voltage field on pin A5 and use it to detect if someone is too close to our Arduino.

Proximity sensor kit for Arduino free from Future. A capacitive sensing evaluation kit from Cypress Semiconductor is being made available free to design engineers by distributor Future Electronics on ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...
