Hello there
I've bought this sensor, I've just used it, I've read online, it says 48 of preheat. I have just used it
and what I read is a negative voltage that fluctuates to postive voltage in mV. I noticed that this voltage increases
as smoke increases but it is not stable, it goes to negative and back to postive.
Anyone here used it ? what's wrong? I think the wiring is correct.
Thanks
