The ultrasonic distance sensor (HC-SR04) is a widely used electronic component for non-contact distance measurement. It operates on the principle of echo-ranging, where it emits an ultrasonic pulse ...

The Arduino Uno is powered by the ATmega328P, an 8-bit microcontroller that runs at 16 MHz. It has 32 KB of flash memory, 2 KB of SRAM, and 1 KB of EEPROM. The board has 14 digital I/O pins (of which ...

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 ...

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 ...

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 ...

Abstract: Traffic congestion remains a widespread issue, often stemming from inefficient signal timing, weak enforcement, and poor traffic management. Traditional traffic lights follow fixed timers, ...
