Calibration Chamber

The calibration chamber was designed and constructed as a dedicated environment for testing and calibrating low-cost indoor air quality (IAQ) sensors. This custom double-skin structure enables controlled testing of environmental parameters such as temperature, humidity, CO₂ concentration, and pollutant dispersion. The project focuses on the chamber’s physical design: from material selection and airflow control to sensor mounting, sealing techniques, and environmental isolation. Fabrication was carried out using laser-cut acrylic panels, 3D-printed mounts, airtight gasket seals, and integrated fans and inlets/outlets to simulate dynamic environmental changes. This structure serves as a reusable, scalable testbed to support sensor calibration under repeatable and controlled conditions.
