Crowtail- Moisture Sensor

 This Moisture Sensor can be used to detect the moisture of soil and thus to monitor if the plants in your garden needs some water.

    This sensor uses the two probes to pass current through the soil, and then it reads then resistance to get the moisture level. More water makes the soil conduct electricity more easily (less resistance), while dry soil conducts electricity poorly (more resistance). Compares to the other moistures sensor using the same moisture test method, this module has a super long legs, making it suitable for actually applications. 

Features

  • Connection Mode: A(Analog)
  • Supper long legs

Specification

  • Power supply: 3.3v or 5v
  • Output voltage signal: 0~4.2v
  • Current: 35mA

Part List

  • 1 X Crowtail- Moisture Sensor 
  • 1 X Crowtail 3 Pin Cable

  • Moisture sensoring

Usage

The following sketch demonstrates a simple application of sensing the moisture of the soil.

1.Connect this module to one of analog port A0 of Crowtail - Base Shield with the 3 pin Crowtail cable, and then insert the Sensor into the soil or place it anywhere you want.

2.Plug Crowtail - Base Shield into the Arduino/Crowduino and connnect Arduino to PC via a USB cable.

3.The hardware installation as shown below:

4.Copy and paste code below to a new Arduino sketch.

int sensorPin = A0;    // select the input pin for the moisture Sensor
int sensorValue = 0;  // variable to store the value coming from the sensor

void setup() {
 // declare the ledPin as an OUTPUT:
  Serial.begin(9600);  
}

void loop() {
 // read the value from the sensor:
 sensorValue = analogRead(sensorPin);    
 delay(1000);          
 Serial.print("sensor = " );                       
 Serial.println(sensorValue);                   
}

5.The Result in different condition after open the serial monitor:
