Air Quality Monitoring System :

The commercial meters available in the market are Fluke CO-220 carbon monoxide meter for CO, Am probe CO2 meter for CO2, ForbixSemicon LPG gas leakage sensor alarm for LPG leakage detection. The researchers in this field have proposed various air quality monitoring systems based on WSN, GSM and GIS. Now each technology has limited uses according to the intended function, as Zigbee is meant for users with Zigbee trans-receiver, Bluetoothis a short range communication system, GSM notifies through a message only. No such system is present that monitors various gases present in the environment like CO, CO2, smoke, LPG, iso-Propane, iso-Butane as well as the temperature and humidity in the environment at the same time and monitors these parameters at a remote location, provides extra precaution for the most crucial parameter and provides parameters important to all users such as temperature and humidity to every person in the range of the monitoring system. This paper proposes such system based on WSN, Bluetooth Technology and GSM/GPRS.
