An improved version of the in-house developed electronic nose. The prototype development involves hardware, software and the design and fabrication of case and odour capturing module. One of the main objectives of the development of MNOSE is to provide a lower cost alternative to the commercially available electronic nose and recognition system. The system is also designed to be superior pattern recognition ability. The prototype was developed using off-the-shelf components combined with rapid prototyping techniques. The Metal-Oxide Electronic NOSE (M-NOSE)is able to detect and differentiate different sample odours by recognizing the specific odour profile. The M-NOSE uses an mounted on a PCB. The odour profile are perceived as the individual odour fingerprint for that particular sample and uses artificial intelligence for recognition.
