Abstract

Honeys come in many varieties based on quality attributes and region origin. Electronic nose systems have been adopted and used to classify honey types based on physicochemical parameters. This study was aimed to build a low cost  electronic nose (e-nose) based on metal oxide semiconductor (MOS) gas sensors, and then used to evaluate the qualities of two types of honeys and one non honey based on sugar contents and pH values. Six gas sensors of MQ modules namely MQ2, MQ3, MQ4, MQ5, MQ6, MQ9, and an Arduino microcontroller were used in this system.  Software of Arduino IDE, PLX-DAQ, and Python were applied to record output voltages of each sensor, saved in Excel format, and to calculate trapezoid areas respectively. Honey samples were named as A, B, and C which were. a national brand honey, a local forest honey, and date syrup respectively. The results show higher output voltages for MQ 3, MQ 4, and MQ 6 sensors. The six sensors are able to differentiate between the two honey types and non honey. Sample A has the highest trapezoid area while sample C has the lowest area. This could be caused by higher pH value of sample C.
