HC-SR04 Ultrasonic Distance Measuring Sensor
The HC-SR04 Ultrasonic Distance Sensor is a non-contact distance measuring module that works by emitting ultrasonic sound waves and calculating the time taken for the echo to return after reflecting off an object. This makes it ideal for robotics, automation, obstacle avoidance, and general electronics projects.
The sensor offers reliable distance measurements over a wide range and is easy to interface with common microcontrollers such as Arduino, Raspberry Pi, ESP32, and similar platforms. For applications that require higher precision or compact laser-based sensing, consider the VL53L0X Time of Flight Laser Ranging Distance Sensor.
