Air-Quality Monitoring and Data Collection
+
Built an air quality monitoring system using an ESP32 microcontroller that interfaces with three sensors: a BME280 for temperature, humidity, and pressure; an SPS30 for particulate matter (PM2.5/PM10); and an SCD40 for CO2 levels. The ESP32 runs custom firmware that collects sensor data and transmits it over WiFi via HTTP with JSON payloads to an InfluxDB instance running on my homelab. This enables continuous monitoring and historical tracking of indoor air quality metrics.
