I got 16 of these but unlike the picture that has red, black and blue, I got red, yellow, and green. Yellow is GND and green is signal, opposite to what their tech is telling me. Also remember to connect a 4.7Kohm resistor between signal and 5V. I was able to get the sensor working but took me many trials. This makes an inexpensive and well packaged sensor, you just need to get a suitable plug for it. I use DIN-5 plugs.

Il sensore funziona perfettamente. Ottimo per usarlo con arduino o altri microcontrollori (con porta analogica). Lo consiglio sopratutto per il prezzo e per il fatto che è impermeabile ed ha già il cavo.
