Vehicle Detection: Ultrasonic sensors monitor each parking slot and send data to the Arduino Uno. Slot Availability Display: Real-time updates shown on an LCD using I2C communication. Barrier Control: ...

You would have probably read about the SONAR that’s used in ships. By taking the same concept into a small form factor we get a distance sensor. This sensor is available in multiple variants and I’ll ...

[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 ...

This project simulates a 2D LiDAR system using SR04 ultrasonic sensors mounted on a stepper motor. The system is controlled by an Arduino UNO (Elegoo R3) and scans the surroundings, sending distance ...

Abstract: This research presents the design and implementation of a smart traffic management system utilizing Arduino Mega 2560 and ultrasonic sensors. The system employs multiple ultrasonic sensors ...

For years, ultrasonic sensors have been used in a wide range of applications including fish finders, parking sensors in cars and burglar alarms. In this article, we describe the characteristics 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 ...
