Hey All,
I got my unit working however consistently my PM2 = 0 when i hooked it to my Prometheus i have seen it stay at 0 all the time, the fan is spinning the solder joints seem fine and i believe i followed the wiring correctly based on what i see.
Is there some way to verify that my sensor is functional? i live in colorado so PM=0 might not be off but i figured i would check if theres a way to identify if the sensor is working vs non-working
