Indoor Monitoring

Indoor Monitoring is an ESP32-based environmental monitor for classrooms, labs, and study spaces. The device reads indoor air and comfort metrics, then shows the live status on a TFT display.

What It Measures

• CO2 from a Sensirion SCD4x sensor
• Temperature, humidity, pressure, gas resistance, and altitude from a BME680
• PM1.0, PM2.5, PM10, and AQI from an Adafruit PM2.5 sensor
• Sound level from an I2S microphone

Code Structure

• Code/src/main.cpp: main Arduino firmware, sensor polling, AQI calculation, button navigation, and TFT display pages
• Code/platformio.ini: PlatformIO board, framework, and library configuration
• Code/lib/TFT_eSPI/: bundled TFT display library/configuration used by the firmware
• doc/: static project website for GitHub Pages
