Ultrasonic Sonar Sensor HC- SR04
Description :
The HC-SR04 ultrasonic sensor module is a compact, four-pin device that uses sound waves to determine the distance to an object. It works by transmitting a high-frequency ultrasonic sound pulse from one transducer and then measuring the time it takes for the echo to return to the second transducer. This "time of flight" measurement is then used to calculate the distance. The sensor is affordable, reliable for short-range measurements (2 cm to 400 cm), and does not require physical contact with the object. It is a popular component for electronics hobbyists and engineers due to its simple operation and ease of integration with microcontrollers like Arduino and Raspberry Pi.
Uses :
Robotics: A key component in obstacle avoidance and navigation for mobile robots and autonomous vehicles.
Distance Measurement: Used to measure distances in a variety of applications, such as for a "smart" tape measure or a parking assist sensor.
Proximity Sensing: Detects the presence of an object without touching it, useful in security systems and automated doors.
Liquid Level Monitoring: Can be mounted above a tank to non-invasively measure the level of liquid inside.
Educational Projects: Widely used in STEM education to teach students about sensors, microcontrollers, and the principles of sonar.
