Works perfectly with a raspberry pi using python but you will have to accept the accuracy limitations which in my care is +/- 3cm's. Depending on the application you may also need a couple of resistors to limit the return voltage, plenty of online resources that explain what and how and cost less than 30p from Maplins.

Great product
Good value for money, especially if you are a 'Prime' member!

Good for specific projects, not for real life obstacles
Using this on my Raspberry Pi 4B robot.I'm getting a LiDAR sensor as this one does not detect some materials at home.

Great Value for money, nicely made, so far all three of the units I've wired up have functioned correctly

Great little sensor 4 wire connection.
I use these to measure water level. Connected to an Arduino mega. A short 1 line (map) code can convert the distance into a litre measurement. Very handy.

5V supply only!
Must be used with 5V, not 3.3V. As long as they get a 5V supply, they worked correctly the first time, with NewPing library on Arduino or New_Ping on Particle Photon. Accurate to about 1cm.
