Circuit Uncle‘s soil moisture sensor is available to buy online in India: pretty simple and straightforward to use. It is used for measuring the moisture content in soil or other similar objects. There are two large exposed probes for the sensor, which actually act as a variable resistor. Yes, you guessed it right, more the moisture will be, more the resistor and thus the potential drop, which could be read through Analog input pin of an Arduino UNO or other microcontrollers. Like Circuit Uncle’s sound sensor module, this module is equipped with an LM393 comparator, which enables us to gather a digital output from the sensor, if the moisture is above a threshold. The threshold is controlled through the onboard potentiometer.

Use it to build an automated plant or crop watering system, and make it IoT enabled. These sensors are easy to use,
just insert it into the soil and then read it.

Pin Connection Scheme of Soil Moisture Sensor with Arduino or other microcontrollers

VCC: 3.3V-5V
DO: Digital output interface(0 and 1)
AO: Analog output interface

Example Arduino Code to read soil moisture value at every 1 second

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

void setup() {
// declare the ledPin as an OUTPUT:
void loop() {
// read the value from the sensor:
sensorValue = analogRead(sensorPin);
Serial.print(“sensor = ” );

Features of Soil Moisture Sensor
Dual output mode: analog and digital output
