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

Great little ultrasonic distance measure sensors, they are 5v though!
These sensors are great for distance measuring with many small microcontroller projects. It's worth noting they require 5v (not 3.3v) therefore a bit trickier to use with the likes of ESP8266. It's worth noting it works intermittently with 3.3v but will be unreliable.

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 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.

Works really well. Don't expect perfect readings though without some good error correction code in your sketch (for Arduino). Particularly if bouncing off of something like skin instead of a hard material - the signal can become very jittery.

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

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.
