Measure air pollution in your neighborhood with the most popular PurpleAir sensor. This sensor measures PM2.5 which consists of particles like smoke and dust.
Because PM2.5 is absorbed directly into your body through the lungs, the EPA considers it the most dangerous of particulates.
Designed for outdoor use, this monitor is perfect for residential, commercial, or industrial users looking for a reliable way to collect real-time data on PM2.5. This type of pollution particulate pollution consists of small particles like smoke and dust and is considered to be the most harmful to our health.
Improving upon our most loved and original classic sensor, this updated version makes it easy to replace the laser counters.
Connect this sensor to WiFi and it transmits data to the PurpleAir Real-Time Map, which is accessible on any smart device.
The PurpleAir Classic Plus is available with an optional SD-Card Data Logger for offline data collection.

Monitor works great! I really like that there’s two lasers included in the device for validation. I placed the sensor in the backyard and programmed a little 7” TFT display for pulling real time AQI, looks awesome!

It works, I didn't put it up for it's beauty :)
I put up a purpleair classic plus, where I am there are not a lot of monitors so adding another one really helps the community. Other than it just staying "up" and working, there isn't much else to really think about it.

Our System Not Working
Over the years, we have purchased a total of 4 Purple Air sensors. Right now, they show up on the "Purple Air Map" as gray circles only, because they still aren't communicating real data. We have called customer service once already, unfortunately we will be calling again.
