Capacitive Soil Moisture Sensor V1.2

This is a soil moisture sensor that measures soil moisture levels by capacitive sensing rather than resistive sensing like other sensors on the market. The Soil Moisture Sensor is made of corrosion-resistant material which gives it excellent service life.

The capacitive soil moisture sensor is used just like the Resistive soil moisture simply insert it in to the soil around your plants and make an amazing low cost real time soil moisture monitoring system.

CAP-SW-12-002
This module includes an on-board voltage regulator which gives it an operating voltage range of 3.3 to 5.5V. It is perfect for low-voltage MCUs, both 3.3V and 5V.

Sample Code



// Simple code for Measuring Voltage from
// Capacitive soil moisture sensor
//
int soil_pin = A0; // AOUT pin on sensor

void setup() {
  Serial.begin(9600); // serial port setup
  analogReference(EXTERNAL); // set the analog reference to 3.3V
}

void loop() {
  Serial.print("Soil Moisture Sensor Voltage: ");
  Serial.print((float(analogRead(soil_pin))/1023.0)*3.3); // read sensor
  Serial.println(" V");
  delay(100); // slight delay between readings
}
