Office Indoor Air Tracker Kit v2 — 5-Node ESP32 Mesh with Raspberry Pi 5 Aggregator

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

Transform any office into a sensor-rich environment with distributed intelligence. This kit lets you deploy five wireless ESP32 nodes that capture temperature, humidity, air quality, and motion, fuse the data over a mesh network, and aggregate everything on a Raspberry Pi 5 for real-time analysis. Tackle indoor climate problems in coworking spaces, R&D labs, or your own workplace.

What You'll Build

You’ll create a fully functional indoor air quality monitoring system. Each ESP32 node reads DHT22 and MQ135 sensors, plus MPU6050 motion data, then relays it via ESP-NOW mesh to the Pi 5 central hub. An MQTT broker collects the streams, a dashboard visualises live readings, and time‑series logs save to an NVMe SSD. Threshold‑based alerts warn when CO₂ or VOC levels rise — all from one cohesive, self‑built network.

What You'll Learn

• Deploy a 5‑node ESP32 mesh network for fault‑tolerant sensor data transmission
• Interface and calibrate DHT22 temperature/humidity sensors and MQ135 gas sensors
• Integrate MPU6050 IMUs to detect occupancy and movement patterns
• Set up an MQTT broker on Raspberry Pi 5 to aggregate multi‑sensor streams
• Build a real‑time dashboard with Node‑RED or Grafana for data visualisation and alerting
