Environment sensing using smartphone

Mobile devices (in particular smartphones and tablets) can be used to monitor quality of life parameters. Today mobile devices use embedded sensors such as accelerometers, compasses, GPSs, microphones, and cameras without considering, for example, the air quality or the pollutants of the environment. This paper presents the possibility to use the smartphones capabilities to gather data from other phones or sensors. Nowadays, monitoring climate condition´s parameters such as temperature and humidity is a prominent factor to control the changes of the environmental condition of living or working places for the human being. This point can be obtained by using distributed devices in different environments that containing high-resolution sensors and a wireless transmission apparatus for transferring data to smartphones. The Bluetooth was chosen as a transmission tool since it is embedded in all smartphones and it can work in the absence of the Wi-Fi connection. Smartphones are the programmable tools to have different kinds of applications that allow communicating with other devices and also gathering, analyzing and verifying data. In this paper, a novel interface by applying a Bluetooth-based sensor to sense Temperature and Humidity for monitoring of the environmental conditions using the android-based smartphone is introduced.
