Whole Home Air Quality Network Kit with ESP32 + Sensor
ESP32 Whole-Home Air Quality Monitor Kit: Track PM2.5 in Every Room at a Glance
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
You'll deploy five PMS5003 laser particle sensors across your home, each connected to an ESP32, transmitting PM2.5 levels via ESP-NOW to a central hub that displays a real-time air quality map on a color TFT screen. This network gives you room-by-room insight, helping you spot pollution hotspots from cooking, dust, or outdoor infiltration—a tool that turns raw sensor data into actionable awareness for your family's health.
What You'll Build
You’ll have a functioning air quality monitoring system with five wireless sensor nodes and a central dashboard. The TFT screen shows each room's PM2.5 level with color-coded indicators, updated every few seconds. You can mount nodes in the kitchen, bedroom, living room, and study, and watch how air changes through the day—no cloud service needed, just local, fast ESP-NOW communication.
What You'll Learn
- Build a multi-node ESP-NOW wireless sensor network with ESP32
- Interface PMS5003 laser dust sensors for precise PM2.5 data acquisition
- Drive a TFT display with a room-by-room air quality dashboard using the Arduino framework
- Design power management with buck converters for distributed sensor nodes

Who This Kit Is For
This advanced kit suits B.Tech ECE/EEE students building final-year projects or Smart India Hackathon prototypes involving IoT and environmental sensing. It’s also ideal for research scholars at IIT/NIT/VIT/BITS exploring indoor air quality, and experienced hobbyists who want a practical multi-node deployment rather than piecing together tutorials.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to chat with the AI companion trained on this exact project. If you need human help, reach out on WhatsApp — we reply within 24 hours.
Can I add more rooms or sensors later?
The ESP-NOW network can theoretically handle up to 20 peers. With slight code modifications, you can scale beyond five nodes.
Does this kit detect other pollutants like CO2 or VOCs?
No, the PMS5003 measures only particulate matter (PM1.0, PM2.5, PM10). For VOCs or CO2, you’d need additional sensors not included.
Is soldering necessary?
Yes, you’ll need to solder the components onto prototype boards. The kit includes a soldering iron and solder wire; basic soldering skills are assumed.
Five PMS5003 nodes via ESP-NOW report PM2.5 to central hub. TFT shows room-by-room air quality map.
