Office Indoor Air Tracker Kit – Predict Office Air Quality with ESP32 and AI

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Stuffy meeting rooms and sealed office spaces concentrate CO₂, VOCs, and humidity that silently drain focus and energy. With this kit, you build a compact device that reads real-time air quality from MQ135 and DHT22 sensors, runs an on-device TFLite regression model to predict AQI, and streams the results to a Node-RED dashboard — giving you actionable insights before air quality drops.

What You'll Build

You’ll assemble a desk-mounted ESP32 monitor that displays live temperature, humidity, and gas sensor readings on the OLED. The microcontroller runs a trained regression model to compute an air quality index (AQI) from those raw signals. A Node-RED flow then plots the predictions over time, so you can track office air trends and share data with colleagues or building management.

What You'll Learn

• Interface MQ135 and DHT22 sensors with ESP32 and extract meaningful environmental readings
• Preprocess sensor data to feed a machine learning model for air quality prediction
• Train a TFLite regression model and deploy it on ESP32 for real-time on-device AQI inference
• Build a Node-RED dashboard that ingests predicted AQI via MQTT and visualizes air quality trends
