Abstract

The use of gas can have both good and bad effects, the good effect is increasing the effectiveness of cleaner heat production and reducing the concentration of pollutants in the air. Gas cylinders that explode as a result of human error or errors in the production process of LPG gas cylinders or gas hoses should receive immediate treatment so that they do not become more dangerous and result in more victims. Efforts can be made to reduce this incident by detecting the smell of gas from leaks in gas cylinders by a gas sensor implemented by a microcontroller. How this microcontroller-based gas leak detector works in a home can be seen in the MQ-2 Sensor. If the sensor detects a gas leak (MQ-2) in the room, the buzzer will light up as an alarm that a gas leak has occurred and the Arduino will give a command to the SIM800L GSM module to send an SMS notification to the home owner's cellphone. This tool works by reading gas levels which are tested using a portable stove with a gas source via a portable gas cylinder which contains the same butane compound as the compound in LPG gas. If the gas level is detected by the mq-2 sensor, an alarm will automatically come on indicating an occurrence. gas leak in the room. then the Arduino nano orders the SIML800 GSM module to send an SMS to the home owner that there has been a gas leak in the house so that the home owner can find out and replace the hose or regulator on the gas cylinder.

Abstract

Air is one of the essential components for the survival of living things, air is a mixture of gases found in layers that surround the earth.Later, We were surprised by the rumors of air pollution happening in Indonesia, Especially in jakarta and beberaqpa other major cities in Indonesia.Without good air will surely be fatal to the respiratory system of humans and other living things on the face of the earth.Carbon (CO and CO2) is one of the materials found in the air and on the ground as carbonate rock, The gas has had a terrible impact on humans and other living things.If a living thing is exposed to that gas in a long time can result in death caused by a lack of oxygen intake. For that, The author performs the design and manufacture of carbon gas levels monitoring tools (CO and CO2) based on NodeMCU ESP 8266.Where the tool works by monitoring CO and CO2 levels that can provide information about CO and CO2 levels that then data from the gas levels will be sent directly to the whatsapp app and also through the LCD display and there will also be a warning alarm from the buzzer.Based on the tests that have been performed, the tool works to maximize the ability to monitor the levels of co and co2 gas sent to the whatsapp app and also be able to provide information via lcd and alarms through the buzzer when the levels of co and co2 exceed the previous threshold when the gas levels have returned to normal then the alarm will cease to sound and become normal
