I have an indoor unit that I use in my garage. It’s started giving really crazy readings, like off the charts high (PM2.5 AQI of 2300+) - I’ve moved the sensor into another room and no change in reading. I’ve checked and it doesn’t look like any bugs or debris have gotten into the sensor. Are there steps I can take to fix this? Thank you!
Hi @rt343, this is the reading your sensor will report when something is inside the laser counters blocking the laser. In this case, we would recommend trying to clean it out using the techniques found in the following article: After Installation.
