Air Quality Monitoring and Control System for a Hospital Room

Abstract

The authors developed a system that allows air quality monitoring and controlling within a hospital room. The system based on temperature and humidity sensors measures the changes in a room's temperature and humidity, displays the achieved data, and uses a Bluetooth emitter/ receiver to allow the remote control of the system parameters. By using remote control from an Android device, the system allows easy integration with other systems like patients' temperature, oxygen saturation levels, or other room parameters like carbon dioxide levels. Another possible use for the system comes from the possibility to sound an alarm on the Android devices of hospital personnel if the room's temperature is above a certain level, which may indicate the presence of fire inside a room. The authors propose the use of cheap sensors and open-source software and hardware. Thus, the system's advantages are: it monitors the quality of air in essential rooms, the air parameters can be improved from distances, dangerous situations can be prevented, is affordable for every hospital. Also, improving the staying conditions in hospitals will improve the quality of medical services, which will lead to an increased quality of life even in poorer countries or cities.
