Implementation of Real Time Approach for Early Warning Gas Leakage Detection

Abstract

LPG (Liquefied Petroleum Gas) gas is the primary source of energy in most households. Recently LPG gas leak has cause significant fire hazard accident and losses. This present work investigates the sensitivity of gas sensor MQ2 and MQ6 hence developed a safety system to monitor LPG concentration with low-cost kit. This monitoring system is also equipped NodeMCU ESP32 microcontroller with interface to the wireless sensor network that is used to transmit the change of gas concentration in the real time information. Gas leak alert is sent to Blynk App every second with the message format.
