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 ...

The quick road test, oh it’s a simple approach to display the distance measurements on the Arduino Serial Monitor. I will use this sensor (or its latest version) in a more complex project in the next ...

tinyLiDAR is a miniature (about the size of a US Quarter) laser distance sensor module that’s super easy to use thanks to a dedicated ultra low-power 32-bit microcontroller.
