Design of IoT-Based SmartMat

Abstract

This paper elucidates designing a complete domestic security and maintenance system with the help of MQ2, LM35, load cells, buzzer, LCD, DC pump, DC gear motor, and brushless fan. The rise in levels of LPG, CO, smoke is controlled and maintained by MQ2, LM35, and fan, regulator turning OFF motor and heat is taken care of by LM35 and DC pump. The load cells are used to keep check of the weight of LPG cylinder for its refilling and avoidance of leakage. We have connected all of this with our app. Through the app, we can constantly and distantly monitor the levels of LPG, CO, and smoke. This app also enables us to remotely control the exhaust fan. This whole sums up to the safety system and maintenance as far as LPG and other gases commonly found in kitchen are concerned.
