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 ...

[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.

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 ...

Likely applications are button designs and proximity sensing. The kit’s board also includes ... The kit works as a stand-alone unit and as an Arduino-compatible shield. It can be used to add a ...

The monitoring of rotation can involve such sensor types as proximity, photoelectric, resolvers, encoders, and tachometer generators. Most determine direction of rotation, speed, and angular ...
