Hi guys !
I'm working on the Mr513 gas sensor, you can find the datasheet here, and a good drawing from Reloadron here. However I don't understand why when I tried to measure the resistance of C and D I have nothing on the ohmmeter ! Has someone managed to get some good results? Also in a wheastone bridge we suppose that there is 3 resistances whom we know their values but in the previous drawing we only know 2 out of 4.
Thank you to share your experiences.
