Abstract
This study aims to help PT. Prima Gasifikasi Indonesia makes a device that detects leaks in gas distribution pipes based on microcontroller technology. This gas detector is connected to several virtual devices that make this tool work well, namely the MQ-2 sensor working as a gas detector, NodeMCU to control the device's controls. As a notification sender to Android, the LED indicates the tool is active, and the buzzer is the provider. Information with a voice indicator. This detector can detect gas to a 'distance 'of less "than '25 cm 'from the sensor. The input on this device, namely MQ-2, will be sent directly to NodeMCU using programming, namely C language when detecting gas. From the device, two conditions will appear, the first condition is LOW when the device does not detect gas and the second condition is HIGH; namely, the device is medium detects gas caused by a leaky pipe, if the device detects gas, the 'systems will command the output in the form of a buzzer as a sound indicator to sound and provide a notification sent via the Internet to Android by giving a message that the gas has been detected
Highlights
Biomass is processed in the form of wood using the Biomass Gasification Engine System (BGES)
Prima Gasifikasi Indonesia, there are many gas pipelines in processing wood into gas, and many people interact directly with these pipes to carry out checking, regulation, and repair
Input's from sensor MQ-2 are sent to NodeMCU as processors late the data in the form of ADC (Analog To Digital Converter), sending data on the gain from the sensor MQ-2 will apply to use the programming language is the C language using software Arduino
Summary
The gases produced from this processing are CO, hydrogen, and methane (CH 4) [1] This gas is flammable and dangerous; if humans are directly contaminated, it can cause various diseases such as lung disorders, reduced blood element concentration, dizziness, and even heart attack [2]. Prima Gasifikasi Indonesia, there are many gas pipelines in processing wood into gas, and many people interact directly with these pipes to carry out checking, regulation, and repair. These pipes can leak due to technical faults and the age of the pipes caused by the weather
