Sensor Ultrasónico HC-SR04

grabcad

This is a compact ultrasonic sensor that measures distance up to 4 meters using sound waves. It uses a transmitter and receiver to emit and detect high-frequency sounds, giving an accurate reading of the distance between the sensor and an object in its path. The sensor has a high accuracy of ±3mm and operates at a frequency of 40 kHz. It also includes an interrupt pin that triggers when the distance falls below a set threshold, making it ideal for applications such as obstacle detection and collision avoidance systems. The HC-SR04 is easy to use and integrate into various projects, from robotics to industrial automation, due to its compact size and simple interface.
