System Overview

A comprehensive environmental monitoring system powered by solar energy with wireless data transmission and real-time sensor integration for air quality trackingDeveloped and validated a comprehensive, energy-autonomous air quality monitoring system powered by solar energy, featuring the integration of PM2.5, CO2, temperature, and humidity sensors into a single device. This system utilizes wireless data transmission to continuously send real-time environmental readings to a portable receiver unit, which provides immediate, on-site visualization through a display and LED indicators, with additional capability for optional laptop monitoring. The project culminated in successful controlled indoor and outdoor testing to confirm the accuracy and long-term reliability of the real-time sensor measurements.
