Despite its significance, many smallholder farmers face challenges with inefficient irrigation methods,
primarily due to the absence of precise soil moisture monitoring. This often leads to improper water usage
and lower crop productivity. To tackle this issue, this paper presents an affordable and practical automated
soil moisture detection system tailored for small-scale farmers. Utilizing a buzzer and LED indicators, the
system provides real-time updates on soil moisture levels, enabling farmers to make well-informed
irrigation decisions. By optimizing water use, it enhances crop health and boosts overall agricultural
efficiency. The system is built on an Arduino-based framework featuring the ATmega328 microcontroller,
which receives data from soil moisture sensors that continuously assess soil conditions. This innovation not

1. INTRODUCTION
In recent years, the agricultural landscape in Bangladesh has faced significant challenges due to
climate variability, intensifying the importance of adopting innovative technologies to enhance
productivity. Agriculture plays a crucial role in Bangladesh's economy, making it vital to
optimize practices amid increasing food and water demand, particularly as approximately 61.2%
of land remains cultivable despite ongoing declines influenced by urbanization and population
pressures. Advanced approaches, such as microcontroller-based soil moisture management
systems, have garnered attention as effective solutions for improving irrigation efficiency and
ensuring crop resilience against adverse weather phenomena (Majumder et al., 2023; Kanimozhi
& Vadivel, 2024).
The current state of agricultural practices necessitates a paradigm shift toward precision
agriculture, where real-time data collection and automated irrigation systems come into play.

Studies emphasize that integrating soil moisture sensors and IoT technology can significantly
enhance decision-making regarding irrigation timing and volume, directly correlating with
increased crop yield and resource savings (Pramanik et al., 2023; Duangsuwan & Promwong,
2023; Surve et al., 2024). For instance, the implementation of automated systems utilizing
Arduino microcontrollers has demonstrated tangible benefits in optimizing water usage while
minimizing waste during irrigation cycles (Sambasivarao et al., 2023; Dong et al., 2024). These
systems can precisely determine when to irrigate, which is crucial in mitigating the effects of
extreme weather events that threaten agricultural output in regions like Bangladesh (Sangeetha et
al., 2024; Dong et al., 2024).
Recent advancements illustrate how intelligent irrigation systems can also incorporate various
sensors, such as temperature and humidity monitors, that collectively provide a comprehensive
understanding of the agronomic environment. This integrative approach aids in optimizing water
use and promotes sustainable farming practices (Wilczek et al., 2023; Hugeng et al., 2023).
Additionally, ongoing research highlights the economization of agricultural practices through
low-cost, efficient soil moisture monitoring solutions tailored for smallholder farmers, thereby
securing higher productivity levels without imposing heavy financial burdens (Zhao et al., 2023;
Rifky et al., 2024).
This paper presents a cost-effective, field-ready automated soil moisture detection system aimed
at small-scale farmers, ensuring efficient water management and improved crop yields. The
proposed system leverages an Arduino microcontroller (ATmega328) to process data from soil
moisture sensors, triggering buzzer and LED indicators to alert farmers about irrigation needs in
real time. By combining low-cost components with efficient monitoring, this system enhances
crop quality, promotes sustainable irrigation, and empowers farmers with data-driven agricultural
decision-making tools.
This work makes several notable contributions to the field of precision agriculture. It introduces a
cost-effective soil moisture detection system built around the Arduino platform, specifically
designed to support smallholder farmers in managing irrigation more efficiently. The system
incorporates real-time feedback mechanisms using a buzzer and LED indicators, allowing users
to instantly understand the current soil condition without the need for external displays or
complex interfaces. Additionally, a fail-safe mechanism is implemented to reduce the impact of
erroneous sensor readings, which significantly enhances the overall reliability and accuracy of the
system. This combination of features ensures that the solution is both accessible and practical for
everyday agricultural use.

4. RESULTS AND DISCUSSION
The system integrates all hardware components, with each module positioned to ensure optimal
performance. The system effectively monitors soil moisture levels and provides timely alerts.
4.1. System Overview and Operation
After setting up the circuit, the code was uploaded to the Arduino Uno board. The code includes a
specific threshold value that determines the critical moisture level in the soil. The moisture sensor
continuously measures the soil's moisture level.
 System Response to Soil Moisture Levels:
 Below Threshold: If the moisture level falls below the predefined threshold, the
moisture sensor sends a signal to the Arduino board, triggering the following actions:
 The buzzer is activated to provide an audible alert.
 The red LED lights up, signaling that the soil is too dry and requires watering.
 Above Threshold: Once the soil is watered and reaches the desired moisture level, the
system responds by:
 Turning off the buzzer and red LED.
 Lighting up the green LED, indicating that the soil moisture is adequate.
 Display of Sensor Readings:
 The moisture sensor's readings are consistently displayed on an LCD screen, providing
real-time information on the soil's moisture content. This allows for continuous
monitoring and immediate feedback on soil conditions.
 System Testing and Validation: The entire system underwent thorough testing to ensure
its functionality. The testing process verified that the system effectively monitors soil

20
moisture levels, triggers alerts when moisture is low, and updates the display accordingly.
Figure 11 typically shows the code written in the Arduino IDE, while Figure 12

Based on the data presented in Figure 13, it is evident that the sensor reading has surpassed the
user-defined threshold. This threshold is a critical value set within the system to indicate when the
soil is too dry and requires watering.
Implications of the Sensor Reading:
 Dry Soil Indication: Exceeding the threshold implies that the soil moisture level is
currently below the desired level, indicating that the soil is dry.
 System Response: As a result of this condition:
 The red LED is activated, providing a visual alert that immediate action is required.
 The buzzer sounds, serving as an audible warning that the soil needs watering.
 Display of Information: Apart from these alerts, the sensor reading is also displayed on
the LCD screen, providing real-time feedback on the soil’s moisture level. This ensures
that the user is informed of the exact conditions and can take appropriate measures to
irrigate the soil.
This automated response helps in maintaining optimal soil moisture levels, thereby
supporting healthy plant growth and efficient water usage.

level of dryness

21
Based on the information presented in Figure 14, the sensor reading is below the set threshold
value, indicating that the soil currently has sufficient moisture.
Implications of the Sensor Reading:
 Moist Soil Indication: The sensor reading being below the threshold means the soil
moisture level is above the critical dryness level, indicating that the soil is adequately
moist.
 System Response: In response to this condition:
 The red LED and buzzer are deactivated, signaling that there is no need for immediate
watering.
 The green LED remains illuminated, providing a visual confirmation that the soil
moisture is at a satisfactory level.
 Display of Information: The sensor reading is also displayed on the LCD screen, giving
real-time feedback on the moisture content of the soil. This allows the user to monitor the
conditions and ensures that the soil remains in an optimal state for plant growth.
This response ensures that irrigation is only applied when necessary, promoting water
conservation and supporting healthy plant growth.

6. DISCUSSION
The proposed microcontroller-based soil moisture detection system faces certain limitations,
particularly in its ability to adapt to different soil types and the necessity for precise calibration
across various agricultural conditions. These challenges could affect its suitability for a wide
range of crops and soil compositions, potentially leading to less effective irrigation strategies in
areas with heterogeneous soil properties. To mitigate these issues, future improvements will focus
on refining dynamic threshold adjustments to ensure adaptability across diverse environments.
Additionally, advanced sensor calibration techniques, possibly integrating machine learning
algorithms, will be explored to enhance predictive accuracy. Currently, the system relies on local
alerts via LEDs and buzzers, limiting its reach to immediate surroundings. Incorporating wireless
communication capabilities could enable remote monitoring and control, making it more practical
for farmers managing large agricultural plots. Further research will also evaluate energy-efficient
solutions, such as solar power integration, to improve sustainability in resource-limited settings.
Strengthening these aspects will significantly boost the system’s accuracy, adaptability, and long-
