The Hydro chlorofluorocarbon(HCFC) and Chlorofluorocarbon(CFC) causes ozone layer depletion and pollutes the atmosphere. The usage of LPG without precautions creates fire accidents. The CFC released by air conditioners and refrigerator cause health issues. To solve these health problems and for safety purpose, this paper proposes for monitoring system to realize in indoor environmental pollutants. This system consists of ARM LPC 2148 microcontroller, a sensor module (mq-5 & mq-135) and a

... s Fidelity (WIFI) for communication. The data acquisition, monitoring and alarm are achieved by the proposed system. The experiments results reveal that data acquisition and transmission is reliable. Furthermore, new sensors can be integrated and an application can be developed to monitor the events in home environment.
