Hi

For (at least) the last 24h, my PM2.5 readings are randomly spiking for about 5 seconds before going back to nominal levels. The spikes aren’t happening at some fixed interval, so not sure if there’s a pattern. Not sure what’s going on. Can someone please help me troubleshoot? Thanks

@Tai_AirGradient for reference, this is what the monitor’s activity read for the last 30 days in 1 hr buckets:

As you can see, it was reading somewhat regular readings, but all of a sudden, it’s changed since about June 20th.

Hi again @adyavanapalli ! I’ve consulted the team, and we agreed that we should investigate it further. Could you please contact us via https://www.airgradient.com/support ?

Please refer to this thread, and attach photos of the power adapter you use with the AirGradient monitor (a photo of the side of the adapter that has clear electrical information printed on would be appreciated). Thank you in advance!
