Does anyone know if this will work with apm2.8 flight controller?

Apm 2.8 is arduino compatible you should have no problems.

Does this work with a micro:bit?

Yes but you will need a separate power supply to power to sensor. Needs 5v but 4.5v should work.

is the sensor waterproof??

Hi Georgina, Thank you for your question. Sorry but those sensors are not waterproof. We hope this helps. If you need more information, please feel free to let us know. Have a nice day! Kind regards, ELEGOOEU

I am looking to sense a movement of 1mm - is this switch that accurate?

We could not achieve that accuracy, but it is very dependent on surfaces and surface angles. We were trying to measure distances to people.

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 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.
