The HC-SR04 Ultrasonic Distance Sensor Module is a highly accurate proximity sensor that uses ultrasonic waves to measure distances with precision. It is widely used in robotics, obstacle detection, automation, and IoT projects. This sensor emits ultrasonic pulses and calculates the distance based on the time taken for the echo to return.
Compatible with Arduino, Raspberry Pi, ESP32, and other microcontrollers, the HC-SR04 sensor is ideal for distance measurement, security systems, obstacle avoidance, and smart automation.
Key Features:
✅ High Accuracy: Measures distances from 2cm to 400cm with an accuracy of ±3mm.
✅ Easy to Interface: Works with Arduino, Raspberry Pi, ESP32, and other MCUs using a simple trigger and echo method.
✅ Fast Response Time: Provides instantaneous distance measurement for real-time applications.
✅ Wide Applications: Used in robotics, parking sensors, obstacle avoidance, water level detection, and automation.
✅ Low Power Consumption: Works efficiently with a 5V power supply, making it suitable for battery-operated projects.
