The Gas leak can cause fire explosion and suffocation. The Water leak can cause the short circuit at our places and can also cause the flood or water overflow at home. If water comes in contact with a live wire then it may lead to the fire. Our system will detect water and gas leakage so we can save many homes from such situations.

INTRODUCTION The aim of our project is to detect L.P.G gas leakage or dripping water in small scale factories or in home appliances [1]. Gas leak and the fluid leak is a major issue at many places. L.P.G is simply propane or butane, are flammable mixtures of bottled gasses used as fuel in heating gadgets, cooking mechanisms, and vehicles[4]. The L.P.G gas leak is very harmful as it can cause suffocation and people can die because of it. Major effects of water leakage are: 1. Flood 2. Wastage of water Major effects of Gas leakage are: 1. Fire 2. Blast 3. Suffocation Existing water leakage and L.P.G gas leak detection systems are very costly. Water leak detection can cause 2000. Gas leak detection system separately can cause Rs 5100 or more. So, we are combining both the technology to reduce the cost and to provide safety for our home. Block diagram of this system shows all the component and flow of the system (refer Fig:-1). Fig -1: Block Diagram of Water and Gas Leakage System 2. HARDWARE IMPLEMENTATION The Block Diagram of the entire system is as shown in the Fig-1.As shown in the figure there are different components explain further. The main components of the system are- 1. Arduino Board 2. Water sensor 3. MQ-6 Gas sensor 4. GSM module 5. ESP8266 Wi-Fi module 6. M-Q6 Gas Sensor with esp8266(connection diagram) 7. Water Sensor with esp8266(connection diagram) Connection and explanation of main components are given ahead.
