Data Logging for Air Quality

For many of us, air quality was top of mind this summer. PurpleAir was there to help.

What gets people interested in air quality is different for everyone - for some it's wildfire smoke, for others it's general pollution, and for the founder of PurpleAir, it was a nearby gravel pit.

From a humble beginning, PurpleAir has grown to a network of almost 11,000 air quality sensors in 80 countries. While their sensors are designed to share data over WiFi, the company turned to the SparkFun OpenLog when they needed the ability to log data while not connected to a network. This change also has the added benefit of allowing them to capture important information anytime a sensor crashes!

    For those interested in building their own air quaity moniotr, I pulished a small PCB to integrate a few environmental monitoring using a PMSA003 and an ESP32 module running ESPHome. I've published the PCB design files for those interested!
