HC-SR04 Ultrasonic Distance Sensor - 2cm to 400cm Range, Precise Object Detection

<p>The HC-SR04 Ultrasonic Distance Sensor is a highly reliable sensor designed for measuring distances between 2 cm and 400 cm with an accuracy of up to 3 mm. Using ultrasonic sound waves, this sensor provides precise distance measurements by emitting sound pulses and calculating the time taken for the echo to return. The HC-SR04 is ideal for applications such as obstacle detection, automation, and robotics. </p> <p>This sensor operates by transmitting an ultrasonic signal and measuring the time it takes for the sound to bounce back after hitting an object. It features four pins: VCC, Trig, Echo, and GND, making it easy to integrate with microcontroller platforms such as Arduino and Raspberry Pi. The compact design and high accuracy make it suitable for a wide range of projects, including distance sensing, object avoidance, and level detection.</p> <strong>Key Features :</strong><ul><li>Wide Measurement Range: Measures distances from 2 cm to 400 cm with an accuracy of ±3 mm.</li><li>Ultrasonic Detection: Uses sound waves to detect objects and calculate distance.</li><li>Compact and Lightweight: Small form factor ideal for embedding into various applications.</li><li>Easy to Interface: Compatible with microcontrollers like Arduino and Raspberry Pi.</li><li>Low Power Consumption: Efficient power usage for continuous operation in battery-powered systems.</li><li>Multiple Applications: Perfect for robotics, automation systems, and distance monitoring.</li></ul>
