Introduction

Compost soil plays a vital role in various studies as a medium to measure temperature. Soil temperature is significantly influenced by the properties of the soil itself, where compost soil tends to have a higher temperature due to the nitrogen content in it. This final project aims to develop a compost soil temperature measurement system using the DS18B20 sensor, which will be compared with the DHT-22 temperature sensor. The temperature data obtained from the two sensors will be managed by the ATmega328 microcontroller, displaying the measurement results in the form of soil and air temperature graphs on the LCD and PC.

Sensor and Microcontroller Selection

The DS18B20 sensor was chosen for its ability to provide accurate temperature measurements in a wide range, as well as ease of use through one cable communication. Meanwhile, the DHT-22 sensor, which is a humidity sensor and temperature, provides additional data that is useful for comparing the results obtained from wet and dry compost soil. The ATmega328 microcontroller, which is the brain of this system, has a reliable performance in processing data from the two sensors. With the right programming, the microcontroller can collect temperature data, process the information, and display the results in real-time.

The DS18B20 sensor is a digital temperature sensor that provides accurate temperature measurements in a wide range. Its ease of use through one cable communication makes it an ideal choice for this project. The sensor can measure temperatures from -55°C to 125°C, making it suitable for various applications, including compost soil temperature measurement.

DHT-22 Sensor: A Humidity and Temperature Sensor

The DHT-22 sensor is a humidity and temperature sensor that provides additional data that is useful for comparing the results obtained from wet and dry compost soil. The sensor can measure temperatures from -40°C to 80°C and humidity levels from 0% to 100%. Its compact size and low power consumption make it an ideal choice for this project.

ATmega328 Microcontroller: The Brain of the System

The ATmega328 microcontroller is a reliable and efficient microcontroller that has a reliable performance in processing data from the two sensors. With the right programming, the microcontroller can collect temperature data, process the information, and display the results in real-time. The microcontroller has a wide range of features, including a 10-bit ADC, a 16 MHz clock speed, and a large memory capacity.

Data Measurement and Processing Process

Temperature measurements are carried out regularly to obtain accurate data. Data obtained from DS18B20 and DHT-22 sensors are taken every few seconds and then stored in the microcontroller memory. The measurement of compost soil temperature, both wet and dry, is then displayed on an LCD screen connected to a microcontroller. In addition, data can also be transferred to a computer for deeper analysis.

Temperature Graph: A Clear Visualization of Temperature Difference

The temperature graph produced provides a clear visualization of the temperature difference between wet and dry compost soils. The use of this data can provide valuable insights for researchers or farmers in managing compost land, especially in terms of fertilization and maintenance of plants.

Data Transfer to Computer: Deeper Analysis

Data can also be transferred to a computer for deeper analysis. This allows researchers or farmers to analyze the data in more detail and gain a better understanding of the compost soil temperature measurement system.

Benefits and Applications

The implementation of this system not only aims to increase the accuracy of compost soil temperature measurements but also provides insight into environmental conditions that affect the process of compost soil decomposition. By understanding the temperature of the land, farmers can optimize the composting process, so as to produce high-quality compost soil.
