Developing Carbon Monoxide Gas Detectors In Vehicle Cabins

Abstract

A vehicle will produce carbon monoxide (CO) gas when an incomplete combustion occurs. CO is odourless and colourless. The MQ-9 sensor is installed on the vehicle to detect the presence of CO in the vehicle cabin. The detection of CO in the vehicle cabin involves the MQ-9 Sensor, Arduino Mega 2560, and Raspberry Pi. When the MQ-9 Sensor detects CO in the vehicle's cabin, it will send a voltage to the Arduino Mega 2560, and the Liquid Crystal Display (LCD) will display the existence of CO. It will also display the activity of the MQ-9 Sensor. This system will generate an alarm signal and activate the Power Window Motor to pull the vehicle window open 2 inches to increase the Oxygen content in the vehicle. The alarm will sound again when the MQ-9 sensor no longer detects the presence of CO in the vehicle cabin, and the Power Window Motor will raise the window again. At the same time, Raspberry Pi will send information about the presence of CO to the vehicle owner's mobile phone. Indirectly, this approach will help prevent deaths from CO poisoning in vehicles.
