Sensor de humedad del suelo para arduino.

Espececificaciones sensor de humedad del suelo:

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

Service life: About one year (gold-plated surface for enhancing conductivity and corrosion resistance )

Module size: 20X60mm

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(){

Serial.begin(57600);

}

void loop(){

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

Serial.println(analogRead(0));

delay(100);

}
