DEVELOPMENT GAS CLEARANCE SPOTTER TO ALERT CAR USER BY USING ESP 32

Abstract

A device to ensure safety when working in areas exposed to dangerous gases. Especially for vehicle users and industrial or construction workers. The Gas Clearance Spotter monitors the level of dangerous gases such as carbon monoxide, toxic gases or methane which can endanger the health and safety of certain people. The role of devices such as gas clearance spotter is also to provide danger awareness to users when gas levels have exceeded the out-of-control limit, which is the safe limit. This device was created to make it easy for users to carry anywhere and to provide real-time monitoring of areas that are likely to be exposed to dangerous gas leaks. This device is designed using a gas sensor, namely the MQ7 sensor, a digital display using I2C LCD 16x2, and emergency alarms such as buzzer that gives a sound or vibration to detect dangerous gas leaks in industrial areas or public vehicles. This device has successfully function and the gas value will be displayed on the LCD. If the gas level reaches the danger level, then the buzzer and LED will turn ON, and notification is sent to the family member to alert them.
