The RobotDYN Soil Moisture Sensor is suitable for agricultural, irrigation, and botanical gardening operations. When linked to an Arduino or another MCU, it may notify the user when it is time to water their plants and keep track of the soil's moisture content. To activate the soil moisture sensor, just connect the VCC and GND pins to your Arduino-based device (or comparable development board). You will then be given a SIG based on the quantity of water in the soil. One well-known issue with soil moisture sensors is that they only work for a short period of time in a humid environment. To compensate, we gave the PCB a gold coating (ENIG or Electroless Nickel Immersion Gold).

Package Includes:

• 1 x RobotDYN Soil Moisture Sensor

Features:

• This moisture sensor detects soil humidity and is exceptionally sensitive.
• When the soil lacks water, the module produces low simulation values; otherwise, it produces high simulation values.
• You may use this sensor to establish an automatic watering system that will save your plants from withering due to a lack of water when you are away for a lengthy period of time or have missed watering time.
• These sensors may make your garden smarter and help your plants grow more pleasantly.
• The surface has been treated with plating to increase electrical conductivity and corrosion resistance.
• The setup is simple.

Description:

The RobotDYN Soil Moisture Sensor is used to measure the amount of moisture in the soil. The moisture content of the soil may be used to calculate the amount of water in it. A RobotDYN Soil Moisture Sensor is made up of two conducting probes that act as a probe to measure this quantity. It can compute the soil moisture content based on the difference in resistance between the two conducting plates. The resistance between the two conducting plates is inversely proportional to the quantity of moisture in the soil. When the soil is deficient in water, the module will provide low simulation values; otherwise, it will produce high simulation values.

Principle of Work:

We simply need to attach the fork-shaped conductive probe to the soil since it has two exposed conductive plates that act as a variable resistor, increasing in resistance depending on the moisture content of the soil. The resistance of the probe is inversely proportional to the instrument's soil moisture. Soil conductivity increases with soil wetness, decreasing resistance. Soil conductivity diminishes when soil moisture content increases, resulting in higher resistance. This sensor provides an output voltage by measuring resistance, allowing us to compute the moisture content.

 

Pinout of the Module:

 

 

Out (Analog Output) pin outputs an analog signal ranging from 5V to 0V.

GND stands for ground.

The sensor is powered by the VCC pin. It is recommended that the sensor be powered from 3.3V to 5V. Please keep in mind that the analog output will vary depending on the voltage supplied to the sensor.

 

Applications:

• Gardening monitoring system
• Watering system

Circuit:

The module's Ground and VCC pins must be connected to the Arduino Board's Ground, and the Out pins to pin A0 on the Arduino Board.

 

 

 

Library: 

no library is needed.

Code:

int moisture = 0;
int percentage = 0;
void setup()
{ Serial.begin(9600); // serial monitor baud rate
  pinMode(A0, INPUT); // PinMode set, pin for moisture sensor
}

void loop()
{
  moisture = analogRead(A0); // reading value 
  percentage  = map(moisture, 0, 1023, 0, 100); // changing to percent
  Serial.print("Moisture= ");
  Serial.print(percentage); // Print percentage
  Serial.println("%");
  delay(1000);
}

Once the sketch has been uploaded, open a Serial Monitor window to view the Arduino's output. you can see the soil moisture percentage on SerialMonitor with intervals of 1 second.

Comparisons:
The primary problem with resistive RobotDYN Soil Moisture Sensors like this one is corrosion of the sensor probes, which occurs not only because the sensor is in touch with the soil, but also because a DC current is flowing, causing electrolysis of the sensors. To address the issue, individuals have resorted to capacitive probes. Capacitive measurement has certain advantages over resistance measuring in that it not only prevents probe corrosion but also provides a more accurate readout of soil moisture content. It does not, in fact, measure moisture (as water is a bad conductor of current), Instead, it measures the ions that are dissolved in the fluid, thus adding fertilizer, for example, will reduce soil resistance even if no water is provided. Capacitive measurement essentially measures the dielectric generated by the soil, with water being the most critical ingredient in forming that dielectric. also, this sensor lacks any indicator LEDs or Digital output and amplification circuits like the one included with (Soil Moisture Sensor & Soil Hygrometer Detection Module).
