I have this huge spikes in the PM 2.5 graph. They do not correspond to any special activity that I might be doing at home. This has been happening for around 30 hours. When the readings are not that extreme, it either shows from 0 to 3 or it shows “-“
The valley that we see at the CO2 graph is because I took the unit outside to see if it would reset the sensors.
Is my pm2.5 sensor broken?
