Walking safely and confidently can be a challenging task for visually impaired individuals, but with the help of technology, we can make it easier for them. This DIY Blind Stick is an innovative yet ...

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 ...

The ultrasonic radar system is a compact and efficient device designed to detect objects and measure their distance and direction in real time. It consists of an ultrasonic sensor, which emits sound ...

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 ...

The time required for the sound waves to bounce back to the sensor is assessed. An ultrasonic fluid level sensor may also be utilized to assess depth, temperature, velocity, pressure, acceleration, ...
