About This Product
Ready to add eyes to your next Arduino or robotics project?
The HC-SR04 is the classic ultrasonic sensor that everyone uses.
It measures distance from about 2 centimeters all the way out to 4 meters pretty accurately.
It works by sending out a ping and listening for the echo—simple and reliable.
It's perfect for obstacle-avoiding robots, distance alarms, level sensors, or any project that needs to know how far away something is.
This is a brand new, generic module, but it's the exact same HC-SR04 design that works with all the standard libraries.
Just four pins to connect: VCC, Trig, Echo, and GND.
