Description
The HC-SR04 Ultrasonic Distance Sensor is a popular and affordable sensor module used in robotics and automation systems to detect objects and measure distance using ultrasonic waves.
It works by emitting a high-frequency sound pulse and measuring the time it takes to reflect back. With a wide detection range and easy-to-use 4-pin interface, it integrates perfectly with Arduino, Raspberry Pi, and other microcontroller platforms.
Whether you’re building a line-following robot, obstacle-avoiding car, or smart parking system — this is the go-to sensor. Get it now from Dream RC, Bangladesh’s trusted robotics supplier.
