Background

Please see the e-nose project page for an elaborate description as well as practical examples.

Function

This PCB connects to a circular DIN100 eight channel Taguchi gas sensor array (see design 0x0F) and forms the data acquisition part of an electronic nose. An external Arduino Nano is needed. So is a power supply. Add an ENC28J60 Ethernet controller shield and you have an IoT device.
