Ultrasonic Sensors

Sun Feb 24, 2019 5:34 pm

How would you recommend attaching multiple Ultrasonic distance sensors to a raspberry pi and using them at the same time.


By a breadboard or are there any other methods?

For testing purposes then a breadboard will be fine, but if you intend to build a longer term project then soldered connections using a custom pcd or even some simple strip board would be better.

Just be aware you can't have all the sensors doing ranging at once you will have to trigger them one after another or the multiple ultrasonic sounds being produced will interfere with each other.

If you buy the new 3.3V compatible ones they will save you having to use resistors to protect your Pi
