Hi. I'm a noobie.
I've bought a turbidity sensor for my course project
https://www.ebay.com/itm/Turbidity-Tran ... 3834639663
it has quite a poor description and I haven't found tutorials about this model, so I don't really know, how to move futher.
There are 3 pins on the turbidity board. VCC, GND, OUT. What does OUT means?
What GPIO should I connect it to?
What is the type of signal does it produce? Digital or analog? How can I check it?
Can I connect it without resister straight to raspberry?
I don't care about the preciseness of the sensor, I just need to make it show some data)
