Arduino Uno with an attached Soil moisture sensor

Specification


This is a simple water sensor, can be used to detect soil moisture. Module Output is high level when the soil moisture deficit,or output is low. This sensor is inexpensive and easy to use but very accurate so the starters and the experts can use all of it's functions.

Can be used in module plant waterer device, and the plants in your garden no need people to manage. Adjustable sensitivity by adjusting the digital potentiometer.

  • Operating voltage: 3.3V~5V
  • Dual output mode,analog output more accurate.
  • A fixed bolt hole for easy installation
  • Panel PCB Dimension: 30mm * 16mm
  • Soil Probe Dimension:60mm*30mm
  • With power indicator (red) and digital switching output indicator (green)
  • Having LM393 comparator chip, stable


Soil Moisture Sensor local circuit

PIN Assignment


  • VCC : 3,3V to 5V
  • GND : External GND
  • DO : Digital output interface (0 and 1)
  • AO : Analog output interface
  • The local circuit - simple, voltage flipping style sensor


How to wire humidity sensor to Arduino UNO

Example Code


Arduino Code:

void setup() {
// initialize serial communication at 9600 bits per second:
Serial.begin(9600);
}

void loop() {
// read the input on analog pin 0:
int sensorValue = analogRead(A0); Serial.println(sensorValue);
delay(100);
}
