Indoor monitoring of respiratory distress triggering factors using a wireless sensing network and a smart phone

A wireless sensing network Bluetooth enabled was designed and implemented for continuous monitoring of indoor humidity and temperature conditions as well as to detect pollutant gases and vapors. The novelty of the work is related to the development of an embedded software using Java2ME technology for a smart phone that materializes a user friendly HMI. Two mobile software modules assure sensor nodes data reading through Bluetooth connection, primary data processing, data storage and alarm generation according with imposed thresholds for air quality parameters. Additional .NET developed software for a Notebook PC platform permits to remotely configure the mobile application and to receive the data logged in the mobile phone. Using the implemented distributed measurement system, including the smart phone, an intelligent assessment of air conditions for risk factor reduction of asthma or chronic obstructive pulmonary disease is carried out. Several experimental results are also included.
