Sensor ultrasonic - HC-SR04

The HC-SR04 ultrasonic sensor is a popular choice for distance measurement and object detection. This sensor works by emitting ultrasonic waves and then measuring the time it takes for the waves to bounce back after hitting an object. With a range of up to 4 meters and an accuracy of 3mm, the HC-SR04 is highly reliable. It is widely used in robotics, home automation, and security systems, as it can effectively detect the presence of objects or obstacles. The sensor is easy to connect to microcontrollers or Arduino boards, making it accessible even for beginners. Its compact size and low power consumption make it suitable for a wide range of applications. Whether you are building a robot or designing an automated system, the HC-SR04 ultrasonic sensor is a valuable tool.
