The HC-SR04 Ultrasonic Distance Sensor is a device that uses ultrasonic waves to measure distance. The sensor consists of a transmitter and a receiver that are interfaced with a microcontroller, such as an Arduino.
The sensor works by having the transmitter send out an ultrasonic pulse, which is then reflected by objects in the environment. The receiver then detects the reflection and sends the time back to the microcontroller, which can then calculate the distance to the object.
The HC-SR04 Ultrasonic Distance Sensor is capable of measuring distances up to 3 meters with an accuracy of approximately 3 mm. The sensor is easy to use with an Arduino microcontroller and is suitable for a wide range of applications, such as creating automatic parking systems or detecting obstacles in a given environment.
The sensor has a small size and low power consumption, making it suitable for projects where space and energy management are important. The sensor is also easy to install thanks to the four holes on the back, which allow the sensor to be easily attached to a surface.
All in all, the HC-SR04 Ultrasonic Distance Sensor is a practical and versatile sensor that can be an excellent addition to any Arduino project.
