Hi all,
If I’m posting this in the wrong spot, my apologies.
I’ve had a look through the forum and can’t find anything that exactly covers my situation.
I have two Airgradient One indoor sensors, brand new, preassembled. Set them both up as far as I cant tell correctly. I also took them both outside to calibrate their CO2 sensors.
Neither unit will consistently show any of their PM sensor data. both will read all PM data as zero almost all the time, except occasionally and for no reason I can discern, one of the units will show reasonable readings on the dashboard. It gets maybe a half a day of readings, and then it goes back to reading 0 again.
Is there something obvious I’m missing here? do I need to open them to take a cover off the sensor or is there a PM sensor calibration that needs to happen?
