Ultrasonic Distance Sensor Module - HC-SR04
Description:
HC-SR04 is a highly popular and cost-effective ultrasonic distance sensor that is widely used in embedded systems and robotics for accurate, non-contact distance measurement. It works by emitting ultrasonic sound waves and measuring the time it takes for the echo to return, making it ideal for detecting obstacles, measuring distances, and enabling proximity-based automation.
Features:
1. Non-contact Distance Sensing
2. Accurate and Reliable
3. Simple Interface
4. Wide Measuring Range
5. High Resolution
6. Low Power Consumption
