This simple sensor uses the same type of particle detector as the #PurpleAir sensor, but instead of logging, it displays a red/yellow/green light based on PM2.5 levels it detects. 

This device's #plantower sensor is factory calibrated, but this kit is not designed for quantitative readings; it's just the most basic setup you can use to get started measuring particulate air pollution -- dust.

Quite a few people have built simple open source, Arduino-based devices around the cheap #plantower particulate air sensor, and this is a bare-bones version that is easy to assemble, and comes pre-programmed. We also offer it [assembled and ready to plug in in the Public Lab Store](https://store.publiclab.org/products/simple-air-sensor "https://store.publiclab.org/products/simple-air-sensor").
