This project demonstrates a low-cost intelligent traffic signal system using Arduino and ultrasonic sensors to reduce congestion caused by fixed-timer traffic lights. Four HC-SR04 sensors detect ...

Bonezegei_HCSR04 is a simple and easy-to-use Arduino library for interfacing HCSR04 ultrasonic sensor module. The library provides functions for measuring distance, setting trigger and echo pins. The ...

I purchased one of each of these cheap sensors recently from aliexpress for testing purposes. Compared with the ubiquitous HC-SR04 (*), I liked the idea of having a combined emitter/receiver, i.e.

In the race to modernize urban infrastructure and meet aggressive sustainability targets, Oman is making a bold leap. A pioneering waste management system powered by Internet of Things (IoT) sensors ...
