Abstract: Internet plays a vital role in our day to day life. without internet we cannot proceed our lives normally. In Internet also there are types one is wireless and other is wired. In that we prefer almost all wireless Internet since we can access it from anywhere. Here the purpose is to monitor and manage the environmental changes occuring using various sensors like humidity sensor, temperature sensor, smoke sensor and light dependent resistor. Here also using automatic ON OFF cooling fan if there is an any increase in temperature, smoke. This can be performed using ARM-Cortex M3 because of low power consumption. Here using wifi network and is connected to laptop for uploading database using bluetooth module with time and date. By this we can see the uploaded database at any time. this is used in industries, power plants, mining and so on.
Keywords: ARM-Cortex M3, humidity sensor, temperature sensor, smoke sensor and Light Dependent Resistor.
