| Summary: | 碩士 === 大華科技大學 === 機電研究所 === 101 === This master’s thesis presents a kind of monitoring and purification device in vehicle for air quality, which includes power unit, electric cord unit, air quality monitoring unit, and air purification unit. The power unit of this device is used to supply power to air quality monitoring unit and air purifying unit, which uses flexible electric cord for connection. The air quality monitoring unit is used to detect the air quality in the vehicle; uses the detective wire circuit to deliver the signal and controls the air purification unit by the signal. The system of this device will alert and make the driver mindful based on content of hazardous air pollutants (carbon dioxide or carbon monoxide). When the device detects high level of volatile organic compound (formaldehyde or benzene), the system will alert the drivers and keep them focus on their way. Furthermore, the device can detect the air quality inside the vehicle. When one of the level of temperature or humidity is too high, the air purification unit will purify the air itself to improve the air quality inside the car, and also ensure the driver have a safety driving.
