Abstract

Lack of survision and ignorance of LPG clynder leaks was a strong reason for the fire. Leaks in LPG cylinders are caused by rubber quality that does not meet standard, improper installation of the regulator, the quality of the cylinder itself and leaks in the valve system. The aim of the final this project is to design a tool capable of detecting and monitoring leaks in LPG cylinders based on the internet of things. System designed uses several electronic components such as MQ-6 gas detector, buzzer as LPG gas leak indicator, exhaust fan to facilitate indoor air circulation when a gas leak occurs, nodemcu esp8266 as a data processing center. When the system detect LPG gas leak, the system will automatically turn on the buzzer as an indicator of LPG gas leak, exhaust fan will turn on to minimize the gas in the room. The research result prove that the system can detect LPG gas in the air, system will automatically detect LPG gas leaks when gas level over 1000ppm and detection data can be monitored via the blynk applicaton that integrated on android. This research can detect and monitor gas on a prototype scale, then a danger notification will be displayed on the blynk app and the buzzer and fan will automatically turn on
