Over the past day my readings have spiked to an inconceivably high number from my indoor sensor, however the 10 minute, 30 minute, etc. reports haven’t moved.
Suspecting some sort of fouling of the sensor I used a vacuum cleaner to attempt to remove debris from the sensor. I also placed the sensor outdoors for a time, and readings haven’t changed.
I’m still somewhat suspicious that the sensor may be obstructed somehow, but the failure of the 10 minute, 30 minute and longer averages to increase over the last day makes me suspect some sort of failure of the software recording my readings.
The LED on the unit has been bright red since the spike.
Suggestions on how to interpret and remedy this situation?
We apologize for the delayed response. We have seen this kind of reading recently. Sometimes, we have seen power-cycling fix the issue. You can unplug it for a couple of minutes or so, and then plug it back in. If that doesn’t work, please send an email to us contact@purpleair.com and we will continue troubleshooting.
@decanio :Did this issue get resolved for you? I am seeing very high readings on my indoor monitor (Red, 168) when the outdoor air quality monitors surrounding me are all in the low green numbers. The high number shows as having been high for 6 hours, all while I was sleeping and there was no indoor activity (no cooking, no fireplace, no smoking etc.). The high number is concerning and I am wondering if the monitor is malfunctioning.
Yes. My original unit was swapped for a replacement unit that Purple Air provided to me. The new unit seems to be reporting believable data now that it has been installed.
