Two HC-SR04 Ultrasonic Distance Modules

Explore ultrasonic distance sensing in a compatible electronics project with a pair of HC-SR04 modules.

✅ Give the controller a distance-sensing input - The ultrasonic module provides the ranging component for a matching project.

✅ Build more than one sensing point - Two supplied modules support separate experiments or suitable positions in a build.

Build ranging into the project

An ultrasonic sensor lets a development project explore the distance to a suitable reflecting surface. Connect the module to the appropriate controller and implement the required timing and interpretation in software.

Check the module's supply and signal levels before connection, especially with lower-voltage controllers. Target angle and material affect readings; the sensor is not a complete navigation or collision-protection system.
