Ultrasonic Sensor Module HC-SR04

The HC-SR04 Ultrasonic Sensor Module is a reliable and cost-effective solution for distance measurement using ultrasonic waves. Designed for Arduino, Raspberry Pi, robotics, automation systems, and obstacle detection projects, this module accurately measures distance by sending and receiving ultrasonic pulses. With its simple 4-pin interface (VCC, Trig, Echo, GND), it’s easy to integrate into various DIY and industrial projects.

Whether you're building an obstacle-avoiding robot or a liquid level detector, the HC-SR04 delivers precise readings with high stability and minimal power consumption. It’s ideal for beginners, students, and professionals working on embedded systems or electronic projects.
