The advancements in soil water content sensing technology have made it easier for farmers to monitor the soil conditions in real time and make adjustments as needed. These sensors can be connected to a central system for remote monitoring, allowing farmers to access the data from anywhere at any time. This level of automation and precision in monitoring soil water content levels is revolutionizing the way agriculture is practiced, leading to higher crop yields and better resource management.
In addition to monitoring soil water content levels, these sensors can also help in detecting other soil properties such as temperature and salinity. This comprehensive data can provide valuable insights into the overall health of the soil and help in making informed decisions on crop management practices. As the technology continues to evolve, we can expect even more advanced sensors that can provide even more detailed and accurate information for sustainable and efficient farming practices. The future of agriculture lies in harnessing the power of technology, and moisture monitoring device are at the forefront of this transformation.

Discussion.
When considering the construction of a smart irrigation or automated plant watering system, the Moisture monitoring device is often the first component that comes to mind. By integrating this sensor with an Arduino, we can create a system that efficiently waters your plants at the appropriate times, preventing both overwatering and underwatering.
In this article, we will connect a Moisture monitoring device to an Arduino to assess the volumetric water content in the soil. This moisture sensor can provide readings in both digital and analog formats. We will process these readings and indicate the output status using an LED for digital signals, while analog signals will be displayed either on the serial monitor or via LED with PWM control. It's important to note that the Moisture monitoring device is also referred to as a soil humidity sensor, and we will use these terms interchangeably throughout the text.
This Moisture monitoring device, or soil humidity sensor, consists of four pins: VCC, GND, Aout, and Dout, all of which facilitate the acquisition of moisture data directly from the sensor.
The operation of the Moisture monitoring device is quite straightforward, as illustrated in the image below. To use it, simply insert the fork-shaped conductive probe into the soil. This probe features two

exposed conductive plates that function as a variable resistor, with its resistance changing based on the soil's water content.
The probe's resistance is inversely related to moisture levels; higher water content leads to better conductivity and consequently lower resistance, while lower water content results in poorer conductivity and higher resistance. This Arduino sensor outputs a voltage that corresponds to the measured resistance, allowing us to assess the moisture level.
Figure 1. The pinout of the Moisture monitoring
device.
- VCC is the power supply pin, which can connect to either 3.3 V or 5 V. Keep in mind that the analog output will differ based on the voltage supplied.
- GND refers to the ground pin of the board that should be linked to the Arduino's ground.
- DOUT is the digital output pin; a low output suggests adequate soil water content, while a high output indicates low moisture levels.
- AOUT is the analog output pin that provides a continuous signal between VCC and ground. Analog to Digital conversion:
Analog Read output = (Input Voltage/Maximum Voltage) * 1024
Note: Arduino Uno supports 10-bit ADC, Which means the resolution of the output is 2A10 = 1024.
We can notice that the sensor reading output goes up to a maximum of Analog value: 876.
Here we are applying 5 Volts to the VCC pin of the sensor, For 5 Volts, we are getting a maximum of
4.28 Volts Approximately in the SIG pin (output pin). Its equivalent ADC value is 876.
Calculation: (4.28 /5) * 1024 = 876 So the output varies from 0 to 876. Note: This range may change based on the hardware manufacturer. Analyze before using the limits.
In terms of the Arduino code for the Moisture monitoring device, it is quite simple. We read the sensor's analog data and adjust the brightness of an LED based on this information. Initially, we define two macros: one for the LED and another for the detectorpin to read data.
int lamppinn=6; int detectorpin=A0;
Next, we have our setup() function. In the setup routine, we begin by configuring the serial communication at a 9600 baud rate. We also define the lampPin as an output and set the pin to LOW. This ensures the pin won't float and accidentally activate the LED.
void setup() { Serial.begin(9600); pinMode(lamppinn, OUTPUT); digitaWrite(lamppinn, LOW);
}
Next, we have our loop() function, in the loop function we print "Continuous signal:" as text on the serial monitor window and then we call the measure_sensor_output() function inside a Serial.println() function so that once the measure_sensor_output() function is executed, it returns the data and it also gets printed on the serial monitor window,
void loop() { Serial.print("Continuous signal: "); Serial.println(measure_sensor_output()); delay(500);
}
We have developed a custom function, measure_sensor_output(), that reads the analog signal from the A0 pin on the Arduino. Within this function,

we start by declaring and defining a variable called detectorValue to store the raw input collected from the A0 pin. This input is represented in a 10-bit range, spanning from 0 to 1023. To convert this 10-bit data into an 8-bit format, we make use of the *map* function. Once the map function processes the data, we assign the modified value to another variable named out_Val. Afterward, we utilize the built-in analogWrite(lamppinn, out_Val) function on the Arduino to generate a PWM signal, which reflects the input data captured by the Arduino's ADC.
This concludes the coding section for the Arduino-based moisture monitoring device project. If you have any inquiries related to the code, please feel free to leave your questions in the comments below.
int measure_sensor_output() { int detectorValue = analogRead(detectorpin); int out_Val = map(detectorValue, 0, 1023,
255, 0);
analogWrite(lamppinn, out_Val); return out_Val;
}
It works, when electrical currents are sent through the legs of the moisture sensor. The sensor then calculates the resistance it's getting. Since water conducts electricity - the wetter the soil is, the less resistance there should be. It's then connected to an Analog Pin and the Arduino can use that for the program.
The Moisture monitoring device needs to know the maximum moisture that the soil can reach, so we can calculate the percentages. This is called calibration. The sensor calibrates right when the circuit is switched on, in the Setup() function. Therefore, it should already be in freshly watered soil, when it is switched on.
Results. We can write software code to use the Moisture monitoring device. We can write the software code in C++ or Python programming languages. During the writing of the program, it is important to control its correct and accurate operation.
void setup() {
Serial.begin(9600);
pinMode(13, OUTPUT); pinMode(12, OUTPUT); pinMode(11, OUTPUT); pinMode(10, OUTPUT); pinMode(9, OUTPUT);
}
void loop() {
int smsensor; s_m_sensor = analogRead(O); Serial.println("Analog value:"); Serial.println(smsensor);
digitalWrite(13, LOW); digitalWrite(12, LOW); digitalWrite(11, LOW); digitalWrite(10, LOW); digitalWrite(9, LOW);
if (s_m_sensor < 175) { digitalWrite(13, HIGH);
}
else if (s_m_sensor < 350) { digitalWrite(12, HIGH);
}
else if (smsensor < 525) { digitalWrite(11, HIGH);
}
else if (s m sensor < 700) { digitalWrite(10, HIGH);
}
else if (smsensor < 876) { digitalWrite(9, HIGH);
}
}
When developing a software application, it is essential to consider all possible scenarios. Our automated systems may experience failures if there are software inaccuracies. After confirming the correct values, we must configure the automated systems accordingly to ensure they function effectively.

Capacitance involves a sensor that utilizes the soil as a capacitor, relying on its ability to store charge to determine water content. Time-domain reflectometry (TDR) measures the duration it takes for an electrical signal to bounce back along a transmission line, with this timing linked to the soil's charge storage and volumetric water content. Notably, TDR signals
encompass a range of frequencies, helping to mitigate errors caused by soil salinity. Similarly, frequency-domain sensors (FDR) utilize the soil in a capacitive role to gauge the circuit's maximum resonant frequency and correlate it with water content.
