    Abstract
    It has been designed a Digital Soil Thermometer with Thermocouple Sensor Based on Atmega8 Microcontroller. The purpose of the design of this measuring instrument is to implement a soil temperature measuring instrument with accurate measuring results. This tool consists of thermocouple sensor based on ATMega8 microcontroller. This tool is tested on (1) regulator circuit 7805, which aims to know the voltage output by measuring the output voltage of the power supply using a digital multimeter, on (2) the microcontroller circuit, using the ISP mode (In System Programming) the microcontroller is programmed directly on the board circuit and is recognized by the downloader program, and on (3) thermocouple sensor circuit, by measuring the air pressure sent to the microcontroller. Tests were performed with several soil samples for comparison. The result of digital soil thermometer with thermocouple sensor based on ATMega mircrocontroller consists of 3, that are (1) in the surrounding environment, the soil temperature is 29.25 ° C and 83.65 ° F, (2) in the humid soil, the soil temperature is 30.25 ° C and 86.45 ° F, and (3) in heated soil, the soil temperature is 36 ° C and 96.80 ° F.

Tujuan dari perancangan alat ukur ini adalah untuk mengimplementasikan suatu instrumen pengukur suhu tanah dengan hasil ukur yang akurat. Alat ini terdiri dari sensor termokopel yang berbasis mikrokontroler ATMega8. Alat ini diuji pada (1) rangkaian regulator 7805, yang bertujuan untuk mengetahui tegangan yang dikeluarkan dengan mengukur tegangan keluaran dari power supply menggunakan multimeter digital, pada (2) rangkaian mikrokontroler, dengan menggunakan mode ISP (In System Programming) mikrokontroler diprogram langsung pada papan rangkaian dan dikenali oleh program downloader, dan pada (3) rangkaian sensor termokopel, dengan cara mengukur tekanan udara yang dikirimkan kepada mikrokontroler. Pengujian dilakukan dengan beberapa sampel tanah untuk perbandingan. Hasil pengujian termometer tanah digital dengan sensor termokopel berbasis mikrokontroler ATMega8 terdapat 3, yaitu pada lingkungan sekitar, tanah bersuhu 29,25°C dan 83,65°F, pada tanah yang lembab, tanah bersuhu 30,25°C dan 86,45°F, dan pada tanah yang dipanaskan, tanah bersuhu 36°C dan 96,80°F.
