HC-SR04 Ultrasonic Sensor Module for Distance Measuring with Arduino or other Microcontrollers (1Pcs)

Product Details of HC-SR04 Ultrasonic Sensor Module

The HC-SR04 Ultrasonic Sensor Module is a popular choice for distance measuring applications due to its simplicity, accuracy, and reliability. It operates by sending ultrasonic waves and calculating the time it takes for the waves to bounce back after hitting an object. The sensor module consists of an ultrasonic transmitter, receiver, and control circuitry.

To use the HC-SR04 module, you typically trigger it by sending a 10µs high level pulse to the trigger input pin. The module then emits a series of ultrasonic pulses and waits for the reflected signal. The time difference between the transmitted and received signals is used to calculate the distance to the object in front of the sensor.

The HC-SR04 module has a wide measurement range from 2cm to 400cm (1 inch to 13 feet) with a resolution of 0.3 cm, making it suitable for various applications such as robotics, automation, and distance measurement tasks. It operates at a 5V DC supply voltage and consumes about 15mA of current during operation.

Due to its straightforward interface and reliable performance, the HC-SR04 Ultrasonic Sensor Module is widely used in DIY electronics projects, educational purposes, and commercial applications where accurate distance measurement and object detection are required.

In summary, the HC-SR04 Ultrasonic Sensor Module is an excellent choice for projects needing precise and non-contact distance measurement capabilities, offering simplicity, versatility, and affordability in a compact package.
