Description

HC-SR04 Arduino Ultrasonic Distance Sensor embedded module

HC-SR04 is an ultrasonic sensor module that is commonly used to measure distance. Arduino, on the other hand, is a microcontroller board that can be programmed to control various electronic devices, including the HC-SR04 sensor. 

In other words, HC-SR04 is a sensor that can detect distance, but it cannot do anything with that information on its own. Arduino is the brains behind the operation that takes the distance measurement from the HC-SR04 sensor and uses it to perform a specific task. 

By connecting an HC-SR04 sensor to an Arduino board, you can program the Arduino to perform certain actions based on the distance measured by the HC-SR04. For example, you could use the HC-SR04 and Arduino to create an automated door that opens when a person is within a certain distance of the sensor. 

So, the reason why people add Arduino after HC-SR04 is to enable the sensor to perform specific tasks based on the distance measurement it provides. 

If you want to learn more about how to use this device, you can check out the datasheet, I hope this helps you. 😊
