The main cause of the disease that affects the human health is due to improper cleaning of waste which provides unhygienic conditions. By cleaning the waste properly, we can avoid the maximum causes of disease . This is so because the waste which gets dumped over a long period of time leads to a multiplication of germs of various kinds. These germs, in turn, produce bad gases while decomposing the waste. Each kind of germs causes certain diseases. When cleaning of the waste is done in a proper manner, one half of spreading diseases can be avoided. This paper is based on smart-bin which detects the emission of gas inside it. Here, the gas sensors which are connected to Arduino is placed inside the bin. Whenever the sensor detects gas emission GSM module connected with Arduino sends an alert message to the specified user.
