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 ...

In the real world, missile systems use advanced radars, infrared sensors, ... Inside the 3D printed enclosure is an Arduino Pro Mini, a HC-SR04 ultrasonic sensor, and a 1602 serial LCD.

The servo rotates from 0° to 180° while the ultrasonic sensor measures distances at each angle. Data is sent to the serial monitor, simulating a basic radar scanner. Open src/radar_detection.ino in ...

Intelligent Headlight Control System: an Arduino prototype with an LDR for ambient light sensing and an HC‑SR04 ultrasonic sensor for vehicle detection. It uses PWM to adjust LED brightness, reducing ...

The design of a robotic ultrasonic system is similar to collision avoidance and parking systems in cars. For example, ultrasonic sensors are embedded on the sides of a robotic vacuum to give it full ...

A low-cost (~$100), do-it-yourself (DIY) ultrasonic water level sensor/datalogger has been designed, constructed, and tested for use in education, citizen/community science, and research settings. The ...
