Learn how to use ultrasonic sensor to control servo motor. The detail instruction, code, wiring diagram, video tutorial, line-by-line code explanation are provided to help you quickly get started with Arduino. Find this and other Arduino tutorials on Ard
After assembling all the things and put the servo on the controller, you can run it now. You can see in the video that you just have to walk by it and the ultrasonic sensor will sense you and the servo will help you open the light! Convenient, right?

I saw Arduino Radar based on HC-SR04 also. It requires a small servo motor to sweep the sensor to find out distance and angle. I wanted to get that functionality without servo so I guessed I will have to use multiple HC-SR04 placed at different angles to cover the area under observation...
Here are the dimensions of the HC-SR04 sensor: Please keep in mind that they can sometimes differ a little bit depending on the manufacturer. Conclusion So, we have covered pretty much everything that we need to know about using the HC-SR04 Ultrasonic sensor with Arduino. It’s a great ...

[lingib]’s dual sensor echo locator uses two HY-SRF05s, but the cheap and plentiful HC-SR04s will work, too. Both sensors are arranged for maximum beam overlap and wired up to an Arduino Uno. One sensor’s emitter is blocked with masking tape, so all it does is listen. ...
