Air Quality Guardian Kit

This kit serves one of our pillars: Air — technology in the service of nature.

Build your own air-quality monitor that measures the gases, temperature and humidity around you, shows them live on a screen, and warns you over WiFi when the air gets unhealthy. Find out what you are really breathing — at home, in class, or on your street.

What's inside the kit?

• ESP-32S 30Pin Dev Board WiFi Bluetooth CP2102 — WiFi brain that reads the sensors
• MQ-135 Air Quality Sensor — Senses air-quality gases (CO₂, smoke, NH₃)
• DHT-11 Temp & Humidity Module — Measures temperature & humidity
• 0.96" OLED LCD Module — Shows live readings on screen
• BB-01 Breadboard 830 Tie Point — Build base (full breadboard)
• BB-J140 Connecting Jumper Wires for Breadboard (140 Wire) — Connections (140-wire set)
• Dust Air Quality Sensor — PM2.5 fine-dust sensor
• MQ-2 Gas Sensor Module — Smoke / flammable-gas sensor

How the idea works

Every part in the kit has a job. Assembled in the right order they stop being loose parts and become a working system — one you build yourself, understand at every step, and see the result of with your own eyes. The included build guide walks you from zero to running.

Your journey: from kit to competition

• Build — assemble the kit and get it running.
• Understand — learn why each part is there and how it works.
• Improve — modify it, add a sensor, tune it, try your own idea.
• Make a project — turn the experiment into a project that solves a real environmental problem.
• Compete — enter your project into local and international competitions.

A good fit for tracks such as:

• Air / الهواء

What you'll learn

• How gas and environmental sensors turn air into numbers
• Reading multiple sensors and showing live data on a screen
• Sending readings and alerts over WiFi (Internet of Things)
• Why air quality matters for health and the environment

Extend & innovate

Add the PM2.5 dust sensor to measure fine particles and the smoke-gas sensor for fire safety. Log your data to a phone dashboard over days, map the cleanest spots in your area, and trigger a fan or alarm automatically when readings spike.
