Smart Air Monitor – Kids’ Science Project

Eco-Air Guardian: Smart Oxygen Monitoring Science Kit for Kids

Product Overview

Introducing the Eco-Air Guardian from Bigyan Project, an innovative STEM educational kit that teaches children about environmental science through hands-on experimentation. This complete science project demonstrates the crucial relationship between trees, oxygen levels, and air quality in our ecosystem. The kit features a dual-zone display showing green areas with trees versus polluted urban environments, with real-time air quality monitoring through an MQ-2 gas sensor. When oxygen levels drop or pollutants increase, the system triggers an audible alarm, creating an engaging learning experience about environmental conservation.

User Guide - How to Use

To begin using your Eco-Air Guardian kit from Bigyan Project, first assemble all components according to the wiring diagram. Insert the charged 18650 battery into the holder and connect the boost converter to ensure stable 5V power. Position the MQ-2 sensor in the area you wish to monitor. The system will begin analyzing air quality immediately. When pollutants exceed safe levels or oxygen becomes too low, the buzzer will sound. For the educational demonstration, compare readings between the green zone (with plants) and polluted zone to see the dramatic difference trees make in air quality.
