The US EPA Air Quality Index - which uses a 24-hour running average - for both 2.5μm and 10.0μm particle sizes, derived from a Sensirion SPS30 particulate matter sensor. Healdsburg, CA. I'm in the LNU Lightning Complex (Walbridge / Stewarts) fire zone!

Sensirion SPS30 particulate matter sensor via a Raspberry Pi Zero W. Healdsburg, CA.

UNDER TESTING! Real-time monitoring of air quality and pedestrian traffic for the "School Street" initiative. This system correlates traffic restrictions with pollution levels to assess the impact on children's health. Powered by Arduino Uno R4, BG96 NB-I

UNDER TESTING! Telemetry and diagnostic data for the School Street Monitor node. Tracks power levels, signal strength, and internal sensor parameters for calibration verification.

An embedded system based on ESP32 device and ThingSpeak.
