Rancangan alat akuisisi data temperatur dan tekanan udara berbasis mikrokontroler H8/3069F menggunakan sensor temperatur digital DS18B20, sensor tekanan udara analog MPX4155A. Sistem ini juga dilengkapi informasi waktu, posisi dan ketinggian yang diperoleh dari GPS Garmin 18 LVC. Perangkat lunak yang bekerja pada mikrokontroler dibuat menggunakan bahasa C yang dikategorikan sebagai bahasa mid¬level yang mudah diimplementasikan pada mikrokontroler. Adapun komunikasi sensor DS18B20, sensor MPX4155A dan GPS ke mikrokontroler masingmasing menggunakan 1¬wire, ADC, dan RS232. Selanjutnya, hasil akuisisi ditampilkan dalam bentuk Graphical User Interface (GUI) yang dibuat dengan bahasa pemrograman Python dan database berbasis MySQL.
