Water/Liquid Level Detection Sensor Module is very easy to use. Simply, If the board has water or another fluid covering all the wire, then it will output a maximum analog value reading. Hence, since analog values read by an Arduino range from 0 (lowest reading) to 1023 (highest reading), a board completely submerged with a liquid will have a reading of 1023 by an Arduino. If the board is halfway covered, the Arduino will read a reading of about 512. Accordingly, if the board is 1/4 covered by a liquid, then the Arduino will read about 256. And if no liquid is on it at all, then you will obtain a near 0 reading.
