This is a simple soil humidity sensor aims to detect the soil humidity. If the soil is in lack of water, the analog value output by the sensor will decrease, otherwise, it will increase. If you use this sensor to make an automatic watering device, it can detect whether your botany is thirsty to prevent it from withering when you go out. Using the sensor with Arduino controller makes your plant more comfortable and your garden smarter.
  • Power Supply Voltage: 3.3V or 5V
  • Working Current: ≤ 20mA
  • Output Voltage: 0-2.3V (When the sensor is totally immersed in water, the voltage will be   2.3V) 5V power supply,the higher humidity, the higher the output voltage
  • Packaging : Electrostatic bag sealing
  • Sensor type: Analog output
  • Interface definition: Pin1- signal, pin2- GND, pin3 - VCC
Sample code:
# Example code for the moisture sensor
# Connect the sensor to the A0(Analog 0) pin on the Arduino board
# the sensor value description
# 0 ~300 dry soil
# 300~700 humid soil
# 700~950 in water
void setup(){
void loop(){
Serial.print("Moisture Sensor Value:");
