Validating The IAQ System

Chamber Calibration and Sensor Performance Validation

This project focuses on the design and validation of a controlled calibration chamber for indoor air quality (IAQ) sensor evaluation. The study includes simulation-based optimization of airflow patterns, repeatability and stability tests, and statistical comparisons between low-cost sensors and a reference monitor. By establishing robust calibration protocols and validating sensor accuracy, the work aims to bridge the gap between high-precision instruments and accessible sensor solutions in real-world applications.
