This humidity sensor can detect water and other liquids covering the area of the card. If the card detects water or other liquid covering the entire card, then it will produce a maximum analog value reading.
Since the analog values read by a Arduino range from 0 (lowest reading) to 1023 (highest reading), a board completely submerged with liquid will have a reading of 1023 by a Arduino. If the board is half covered, a reading of about 512 will be read by theArduino. If the card is covered with a liquid, then theArduino will read about 256. And if there is no liquid, then a reading close to 0 should be obtained.
