I need a circuit built per the attached schematic. The gas sensor will be a ME3-H2S sensor.
I want to be able to detect trace amounts of H2S so amplifying the signal as much as possible without too much noise is optimal. I want to either read the output with a multimeter or use an arduino.
I am professionally doing PCB designing in an R&D organization and also MS in Electronics in parallel.
I can design PCB as per your specifications in a short duration and with accuracy.
Thanks.
