    KARAKTERISASI SENSOR GAS MQ UNTUK SISTEM HIDUNG ELEKTRONIK
    (2020-01) Fadlilah, Annisa; Minarni, Minarni
    Gas sensors of MQ series are economical sensors which often used in an electronic nose system. This study aims to characterize six gas sensors of MQ series for an electronic nose which are used to evaluate honey quality. The sensor used were MQ 2, MQ3, MQ4, MQ5, MQ6, and MQ9. The reason for choosing the MQ types are based on volatile compounds contained in honey types. The six sensors were connected to an Arduino microcontroller. An acquisition program using Arduino IDE was designed and used to obtain output voltages from each sensor. The six sensors were characterized based on their respons on samples of alcohol, honey, and date syrup. The results showed that only 3 sensors are sensitive to honey and date syrup, namely the MQ 3, MQ 4 and MQ 6 sensors while the other sensors such as MQ 2, MQ 5 and MQ 9 are sensitive to air, smoke and carbon monoxide
