ENVIRONMENT SENSING USING SMARTPHONE
ENVIRONMENT
SENSING USING SMARTPHONE
Abstract
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.
The power supply consists of a step down
transformer 230/12V, which steps down the voltage to 12V AC. This is converted
to DC using a Bridge rectifier and it is then regulated to +5V using a voltage
regulator 7805 which is required for the operation of the microcontroller and
other components.
