Air Quality Monitor (PM2.5, CO2, TVOC) with OLED Display
Build a laboratory-grade indoor air quality monitor measuring particulate matter, carbon dioxide, and volatile organics.
Project Overview
Measure indoor environmental parameters with PMS5003 laser particulate sensor and Sensirion SCD40 NDIR CO2 sensor.
Metrics Tracked
- PM1.0, PM2.5, and PM10 Particulate Density (µg/m³)
- True NDIR CO2 Parts-Per-Million (PPM)
- Total Volatile Organic Compounds (TVOC Index)
- Local graphical trend logging on 1.3" I2C OLED
