Soil Moisture Sensor Module

As the name implies, a soil moisture sensor measures soil moisture level. This can be particularly helpful if you want to accurately determine when plants need to be watered or assess how fast water drains at a specific location.

Technical Specifications

Operating Current: 15mA
Operating Voltage: 3.3V to 5V DC
Output Digital: 0V to 5V, Adjustable trigger level from preset
Output Analog: 0V to 5V based on infrared radiation from fire flame falling on the sensor
LEDs indicating output and power

Digital Output Option:

Sample code:

Analog Output Option:

int Moisture_signal = A0; //Define the Analog pin# on the Arduino for the soil moisture sensor signal

void setup() {

Serial.begin(9600); // Start the serial communication

}

void loop() {

int Moisture = analogRead(Moisture_signal);

Serial.print("Soil Moisture Level: ");

Serial.println(Moisture);

delay(200);

}

Digital Output Option:

int Moisture_signal = 4; //Define the Digital Input on the Arduino for the sensor signal

int Sensor_State = 1;

void setup() {

pinMode(Moisture_signal, INPUT); //Step pin as input

Serial.begin(9600); // Start the serial communication

}

void loop() {

Serial.print("Soil Moisture Level: ");

Sensor_State = digitalRead(Moisture_signal);

if (Sensor_State == 1) {

Serial.println("Soil is moist");

}

else {

Serial.println("Soil is dry");

}

delay(200);

}
