DESCRIPTION:

• The HC-SR04 Ultrasonic Distance Sensor is a popular and affordable device used for distance measurement and object detection.
• It works by emitting ultrasonic sound waves at 40 kHz from its transmitter. When these waves encounter an obstacle, they reflect back to the receiver.
• The sensor measures the time delay between transmission and reception of the ultrasonic pulse to calculate distance using the formula:
• Distance = (Time × Speed of Sound) / 2
• A 10 µs trigger pulse starts a measurement cycle, making it easy to use with microcontrollers such as Arduino, ESP32, or Raspberry Pi.
• Features low power consumption, stable operation, and high precision for indoor or outdoor use.
• Commonly used in robotics, automation, and IoT projects requiring obstacle detection or range measurement.
