The Car Parking Sensor System is designed using the ATmega32 microcontroller and an HC-SR04 ultrasonic sensor to assist drivers in detecting obstacles while parking. The system provides real-time ...

This project implements a car parking sensor system using the ATmega32 microcontroller, ultrasonic sensor (HC-SR04), 16x2 LCD, RGB LEDs, and buzzer. The system measures the distance between the ...

Abstract: In this paper we design and implement an embedded surveillance system by use of ultrasonic signal coding of ultrasonic sensors with multiple pyroelectric infrared sensors (PIR) to detect an ...

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 ...

There is a lot of buzz about electromagnetic (EM) detection and ranging sensor technology, which encompass radar, lidar, infrared (IR), ultra-wide bandwidth (UWB), and many others. However, there are ...
