Lemari pengering ini memakai control Arduiono Uno 328P dan elemen heater sebagai pemanas. Lemari ini juga di lengkapi dengan perangkat mekanik motor DC untuk menggerakkan wadah pengeringan kakao. Alat ini juga dilengkapi Sensor DHT12 merupakan sensor resistif yang nilainya berubah bergantung dari kadar air biji kakao. Sensor berperan mendeteksi suhu dan kelembapan biji diruang pengeringan kakao. Kemudian Tegangan output inverting amplifier dibaca oleh ADC mikrokontroler Arduino UNO 328p, yang kemudian diolah dan ditampilkan pada LCD. Hasil pengujian menunjukkan alat ukur yang dibuat mampu mengukur besar kadar air yang terkandung dalam biji kakao pada range pengukuran kadar air dari 60% hingga 7,5%.</mods:abstract><mods:classification authority="lcc">LC Special aspects of education</mods:classification><mods:classification authority="lcc">TK Electrical engineering.
