Next we connected the water flow sensor’s output to the Arduino board (filled with the sketch) and allowed water flow through the water flow sensor at a steady rate of about 1 Litre/minute. Besides ...

Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

This neural network runs on an Arduino MKR GSM 1400 module. ... Having worked with (+designed+built) water quality sensors, I would take this article with a huge grain of salt.
