HC-SR04 Ultrasonic Distance Sensor Module
The HC-SR04 Ultrasonic Distance Sensor Module is one of the most popular and reliable ultrasonic sensors used for accurate, non-contact distance measurement. It operates by transmitting ultrasonic waves at 40kHz and measuring the time taken for the reflected signal to return, allowing precise distance calculation.
With a measurement range of 2cm to 400cm and an accuracy of up to 3mm, the HC-SR04 is suitable for robotics, obstacle avoidance, water level monitoring, parking assistance, smart dustbins, automation systems, and industrial sensing applications.
The module features four pins (VCC, Trig, Echo, and GND) for simple interfacing with Arduino, ESP32, ESP8266, STM32, Raspberry Pi, and other development boards. Its compact size, low power consumption, and easy integration make it one of the best choices for beginners and professionals alike.
