Design and Development of Carbon Monoxide Gas Leak Detector in Vehicle Cabin

Vehicles are very important in transportation that humans widely use carrying out their activities, including one of them is a passenger car. Safety and security factors traveling the most aspects traveling. The condition often occurs cars frequent leakage carbon monoxide gas vehicle cabin. Usually, CO leaks occur AC hose. So, this research aims to design an Arduino-based leak detector. This with development approach method or Research Development (R&D). produce detector automatically detect cabin based on Arduino Uno. performance can be obtained from content MQ7 sensor, then buzzer will make sound, while LCD display status "Safe/Alert/Very Dangerous" as warning car drivers. DC motor move power window if exceeds threshold more than 25 ppm.
