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 ...

Inside [Klaus]’ device is an Arduino Uno, an HC-SR04 ultrasonic distance sensor, and an Adafruit Wave Shield. Originally, this parking/distance sensor used a small TFT to display the distance to ...

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 ...

[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.

If your car doesn't have that feature, DIY blog Mad Science has put together a tutorial to roll your own sensor system with an Arduino. The build is incredibly simple and you only need a ping ...

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 ...

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 ...
