Web-Based Room Fire Protection Datalog Monitoring Due to Liquefied Petroleum Gas (LPG) Leaks

Abstract

The use of LPG gas is increasingly being utilized by the Indonesian people after the conversion of kerosene to LPG. The use of LPG is more effective, efficient, and easier than that of kerosene. Although LPG gas is more practical to use than kerosene, it still has disadvantages, namely the dangers that can be caused by LPG gas if there is a gas leak. This danger can cause an explosion to a fire that can endanger the surrounding community. Based on these dangers, a tool is needed that can detect leaks and warning signs of leaks and is equipped with initial handling to avoid explosions in the room. This study designs a system to inform residents of houses/companies and reduce the concentration of LPG gas in the room to minimize explosions. This study uses NodeMCU ESP8266, with MQ2 sensor input and relay output for exhaust fans and alarm bells. Based on the results of this system test, the MQ2 sensor captures the concentration of gas leaks in the room, and the device sends data from the NodeMCU ESP8266 to the PHP MySQL database, which controls the exhaust fan to remove gas in the room and the alarm bell as a signal to the occupants of the house if there is a gas leak, and the gas concentration value is recorded by the database for display on the web. For fire protection, there is already a light extinguisher (APAR), namely a fire extinguisher ball.
