PMSA003I reporting 0 for all values fix

I have a couple of air quality sensors I've made by cobbling various Adafruit boards together (Magtag, Funhouse, ESP32-C3) that report to my Home Assistant instance for monitoring. One of these stopped working, where the PMSA003I appeared to be working (fan spinning, no errors), but was reporting 0 for all values.

I verified that the main sensor unit was the problem by switching out the StemmaQT board I have to connect it to the Adafruit boards.

I detactched the unit from the board and gave it a blast of air from a Datavac duster, and it is now working again!
