Abstract: Asthma is one of the widespread chronic diseases. Firstly, the medical background of asthma is given. Pathology and symptoms are presented. Asthma is a chronic condition that mostly affects adolescents. It is a condition that requires continuous monitoring of the symptoms in order to provide an effective course of treatment. It also requires a strict adherence to medication prescribed by the physician. However, the aim of this study is to develop a system, which is based on a periodical data collected by the different sensors. There is no cure for asthma. Symptoms can be prevented by monitoring factors which can trigger asthma attack. So it is very much needed that there should be a system which can monitor air parameter on regular basis and warn the patient when these factor can trigger their asthma attack.
