Hello all,
I am working on a project with a flame rod sensor that outputs a very small voltage in the presence of a flame. The sensor outputs a -0.05mv according to my multimeter. I plan to hook this up to an arduino and want to amplify and maybe run through an op amp comparator circuit to send a clean binary signal to the arduino. Since the flame is either present or no I dont really need a analog signal.
I plan to use an LM324 op amp IC. and am experimenting with an AD623 instrument amplifier but I think the voltage differential is too small at -0.05mv.
Does anyone have any suggestions about how to make this circuit function or other components i should use?
Thanks
