NanoElectroOptical Nose (NEONOSE) for the detection of Climate Change gases

This paper describes a prototype of artificial olfactory system or electronic nose (NEONOSE) containing commercially available MOX and NDIR gas sensors, forming an array of a total of 13 sensors (six MOX and seven NDIR sensors). The electronic circuits have been designed for this application. The prototype consists of two boards (containing different type of sensors) with two microcontrollers that communicates each other by using a digital interface. The processed data is sent via Bluetooth to an Android smartphone, where it is collected and stored using an own developed application developed. Some measurements with different industrial gases have been done for testing the device.
