Cloud Air Quality Logger Variant 20
Build a Real-Time Cloud Air Quality Logger with ESP8266 and ThingSpeak
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
With this kit, you’ll assemble a compact air quality logger that reads real-time pollution levels using an MQ-135 sensor and sends the data every 60 seconds to ThingSpeak’s cloud dashboard. A bright OLED display shows local readings, and you’ll program the ESP8266 to trigger alerts—via ThingSpeak’s React or email—whenever air quality crosses a threshold. Perfect for environmental monitoring, smart city projects, or CBSE/ICSE final year submissions.
What You'll Build
A ready-to-deploy IoT device that continuously measures air quality and logs it to a private ThingSpeak channel. You can place it indoors to detect cooking fumes, dust, or smoke, then view graphs from any browser. Set threshold alerts to get an email when air quality worsens, making it a practical tool for school labs, home safety, or hackathon demos.
What You'll Learn
- Interface the MQ-135 gas sensor with the ESP8266’s analog pin and calibrate the output for reliable air quality index values
- Set up a ThingSpeak IoT channel, generate API keys, and POST sensor data over Wi-Fi at one-minute intervals
- Drive a 0.96‑inch OLED display to show real-time readings and connection status
- Configure ThingSpeak React or MATLAB to trigger an email alert when air quality exceeds a safe threshold

Who This Kit Is For
Tailored for CBSE Class 11–12 students working on IoT-based environmental monitoring, B.Tech ECE/EEE students tackling mini-project requirements, and ATL Tinkering Lab participants who need a ready-to-go cloud logger. If you’re preparing for Smart India Hackathon or simply want to build a smart city sensor prototype, you’ll have your own cloud dashboard running in an afternoon.
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 open your AI companion, loaded with the exact wiring diagram and code for this kit. Still stuck? WhatsApp our Bengaluru build team for a direct reply within hours.
Do I need prior coding or IoT experience?
Some familiarity with Arduino IDE helps, but the AI companion walks you through installing libraries, flashing the ESP8266, and entering ThingSpeak API keys step by step—no prior IoT knowledge required.
Can I modify the dashboard to show additional sensors?
Absolutely. Once you understand the data flow, you can easily add temperature or humidity sensors (not included) to expand your ThingSpeak channel, or customize the OLED display layout.
How accurate is the MQ-135, and which gases does it detect?
The MQ-135 responds to ammonia, benzene, smoke, and CO₂. Its analog output gives a broad air quality index; you’ll learn to calibrate it for your environment—ideal for relative pollution tracking rather than lab-grade ppm measurements.
MQ-135 air quality sent to ThingSpeak every minute from ESP8266. Alerts if quality worsens.
