Environmental approaches don’t exist in the 40 healthcare facilities and more than 1,200 health centers in Senegal. The design of health facilities and their organization are primarily designed to fulfill their primary role: the health of 16 million users each year. However, “all hospital services are exposed to volatile organic compounds (VOCs), only the operating theaters are exposed to a lesser extent”.

The specificity of the care activity leads indeed to a particular confinement of the spaces in the health establishments confronted with three main sources of internal pollutants: the building materials, the furniture (emanating from the formaldehyde which is a priority contaminant …), the human activities and professional activities (cleaning products and disinfectants, care products …). The use of certain products such as anesthetic gases (based on nitrous oxide) or disinfectants and sterilizers in some hospital services, for example, associated with poor ventilation can thus cause pollution impacting staff, patients or visitors.

The aim here is to set up an air quality monitoring and alert system in health establishments.

The system allows the user, such as the building manager, to know, in real time, a variety of environmental parameters such as chemicals and physicals pollutants. The parameters are monitored using selected sensors that collects data and sends those data in a central INFLUXDB database. We make some treatments and print the result in a nice Grafana dashboard.
