Understanding the HC-SR04 Ultrasonic Sonar Sensor
The HC-SR04 Ultrasonic Sonar Sensor is a low-cost, easy-to-use distance measuring device. It is commonly used in robotics and automation applications to measure the distance between two objects. It works by sending out an ultrasonic sound wave, which is then reflected off of an object and detected by the sensor. The time it takes for the sound wave to travel to the object and back is used to calculate the distance between the two objects.
The HC-SR04 Ultrasonic Sonar Sensor is a popular choice for robotics and automation applications due to its low cost, small size, and ease of use. It is also quite accurate, with a range of up to 400cm and an accuracy of up to 3mm. The sensor is powered by 5V DC and requires only two connections for operation.
The HC-SR04 Ultrasonic Sonar Sensor can be used for a variety of applications, from obstacle avoidance to navigation. It is also used in robotics and automation to measure the distance between two objects. The sensor can be interfaced with a
