Background

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

Function

This PCB breaks out the connections to a 6-pin Taguchi type gas sensor. Set the jumper and the heater voltage will be equal to VCC.

Bill of materials

1 pcs. Taguchi gas sensor socket, 6-pin

1 pcs. resistor, form factor 1206 (SMD)

or

1 pcs. potentiometer, 50k

or

1 pcs. fixed resistor, through-hole

1 pcs. two-row pin header

1 pcs. jumper

4 pcs. three-way terminal block connector

Estimated cost

A Taguchi gas sensor, a socket, four three-way connectors and a potentiometer should not cost more than EUR 4,-. You will need two voltmeters to monitor the heater voltage (VH) and the sensor response voltage across the load resistor (VRL). Such panel meters can be found on eBay at a cost of EUR 1,50 each.
