The Compost Soil Temperature Detector Uses A DS18B20 Sensor Based On The ATmega328 Microcontroller
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.
