Soil Moisture Analog Sensor -Arduino Compatible


This Soil Moisture Analog Sensor could detect the soil humidity. It is very useful if you want to build an intellectual garden. Imagine that your device could water your planting while it needs water. Or on occation that you are away on a trip, you don't need to worry about your planting. This sensor is part of our auto-planting system kits (comming soon).

We have three kinds of Water Level Sensor as below :

1、High Sensitivity Water Level Sensor -Black Version

2、High Sensitivity Water Level Sensor -Red Version

3、High Sensitivity Water Level Sensor -Blue Version


1、Power supply: 3.3v or 5v

2、Output voltage signal: 0~4.2v

3、Current: 35mA

Schematic and dimension

Download the schematic diagram



The out pin of Moisture Sensor Module could be connected to any analog input pin of Arduino.

If you have Arduino Sensor Shield, you could plug in and pay.



The example code is very simple.

void setup(){



void loop(){

Serial.print("Moisture Sensor Value:");


You might need to do the test first, to find out what value is the threshold value.
