Oxygen concentrators play a vital role in providing supplemental oxygen to patients, especially in the case of respiratory diseases like COVID-19. Their working principle is primarily based on Pressure Swing Adsorption (PSA) technology, which absorbs nitrogen from the atmosphere and supplies concentrated oxygen to the user. This research paper aims to design and develop an oxygen concentrator using PSA technology, alongside an Arduino Mega controller for enhanced control and monitoring.
