The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

Simple distance measurement project using an HC-SR04 (or compatible) ultrasonic sensor with the Arduino Uno R4 WiFi board. The sketch reads distance and prints it to the serial monitor.

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 ...

Arduino Contactless Dustbin (Ultrasonic + Servo) This project is a contactless smart dustbin that automatically opens and closes the lid using an ultrasonic sensor and a servo motor. When a hand or ...

This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T. I hope this will serve as a backdrop for some interesting ultrasonic distance sensor experiments and projects. A number of ...

[Mike] lives in a temperate rainforest in Alaska (we figured from his website’s name) and uses a 570 gallon oil tank to supply his furnace. Until now, he had no way of knowing how much oil was left in ...

Abstract: Target/object detection, recognition, position, movement speed, etc. is easy when the object is near or easily visible. But, the same doesn't stand true especially when the object is far or ...
