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 ...

We’re used to Hall effect devices as proximity sensors in mechanical ... The circuit is extremely simple, comprising the sensor, an Arduino Nano, and an OLED display. This device is handy ...

Electronic enthusiasts may be interested in a new open source infrared sensor which has been created to support both Raspberry Pi and Arduino powered projects. The IR Detector proximity sensor has ...

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. A5 is used as a ... of statistical averaging to reduce noise in ...

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 ...
