Abstract

Carbon monoxide (CO) gas is a colour less, tasteless and poisonous gas and difficult to detect. Excessive inhalation of CO impacts directly to human health. This mainly affect drivers who have to endure long journeys and have to resort to rest in their vehicles. Air-conditioner (AC) in vehicle is normally turned on during hot weather, which means the engine is also turned on and causing CO leakage into the vehicle. Many people died in car related directly to carbon monoxide poisoning. Therefore, designing a low cost “In-Vehicle Carbon Monoxide Detection System with Auto Window Roll Down (InVCO)” becomes essential to prevent such incident to happen. This purpose of this project is to develop CO gas alert system in detecting CO inside vehicle by using MQ-7 CO gas sensor. To make the system more practical, Arduino Uno is used as a microcontroller to control the whole system. LCD display is used to show the CO concentration inside vehicle in ppm value while LED as well as buzzer are functioned as the alert system. In addition, power window motor is set up to roll down the window automatically to reduce the CO concentration in vehicle. In this project, CO concentration is categorized into two levels according to output voltage of the sensor. This system would automatically give a warning once the hazardous level of CO is detected by activating signals through LCD, LED and buzzer and then roll down the window automatically in order to avoid the carbon monoxide poisoning.
