Water Sensor(SE045)

1．Introduction

This module is called water sensor, it can detect water or other fluid covers the

wire area or not. If the board has water or another fluid covering all the wire, then it

will output a maximum analog value reading. 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, a reading of about 512 will be read by the arduino. 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 a near 0 reading should be obtained.

Specifications:

Voltage: 5V DC

Size:65mm*20mm

Weight:5g
