GeNose is an electronic nose (e-nose) consisting of 4 parts, namely a sampling system, a gas sensor array system, a data acquisition system and a pattern recognition system. The way the e-nose works is by imitating the nose of living things, especially humans, which must be trained and tested. The food sample to be detected is placed in a closed glass container. After a while (around 2-5 minutes) the sampling system will flow the sample VOC into the gas sensor array system, which is then responded to by the eight sensors in parallel with stages starting from baseline (sensor stabilization), sensing (the process of responding to sample VOC) to saturation and purging (cleaning the sensor space).
