Ultrasonic Sensor HC-SR04

Product Description:

The HC-SR04 Ultrasonic Module is designed for non-contact distance measurement with high accuracy. This versatile module integrates an ultrasonic transmitter, receiver, and control circuit into a single package.

Key Features:

• Non-Contact Distance Sensing: Measures distances without physical contact using ultrasonic waves.
• Integrated Components: Includes both the ultrasonic transmitter and receiver, along with the necessary control circuitry.
• Trigger Operation: To initiate a measurement, provide a high-level signal (at least 10 µs) to the TRIG pin.

Operating Principle:

1. Automatic Wave Emission: The module emits an 8-cycle, 40 kHz square wave signal automatically.
2. Signal Detection: If the signal reflects off an object and returns, the module outputs a high-level signal on the ECHO pin.
3. Distance Calculation: The duration of the high-level signal on the ECHO pin represents the time taken for the ultrasonic wave to travel to the object and back. This time can be used to calculate the distance.

Ideal for various applications requiring precise distance measurement and object detection, the HC-SR04 Ultrasonic Module provides a reliable and efficient solution.
