Ventilation of Cars
Embedded Technology For Vehicle Cabin Safety
Monitoring And Alerting System
ABSTRACT
Motor vehicles are the prime source of transportation where vehicles with A/C play a major part. This paper designs an embedded system for a vehicle cabin, which senses the gases like carbon-monoxide and oxygen and displayed at each and every second. If the level of the CO increases than the normal level (30ppm) or the level of the oxygen decreases than the normal level (19%) then an alarm is generated automatically and also ventilation is provided immediately. A warning message is sent to the authorized user via GSM. The advantage of this system is proper detection and faster response time leading to faster diffusion of the situation, compared with the manual methods.
Key words: Atmel microcontroller, ,Embedded System,Gas detecting sensors,GSM Modem,Vehicle safety.
1. INTRODUCTION
Motor vehicles are they not only the prime source of transportation, but also the prime source of pollution. These motor vehicles contribute to over 30% of the hazardous gases that are released into the atmosphere.As the vehicle cabin is small area, any suspended particulate such as dust, fumes, smokes entering in to it through either ventilation or through windows can cause serious health problems to the person inside.The health effects range from minor irritation of eyes and the upper respiratory system to chronic respiratory disease, heart disease,lung cancer and even death .Even if the vehicle is equipped with the air cabin filters that are present inside the cabin so ashe person inside Hence to overcome these types of problems there is a need to monitor several gases such as carbon monoxide (CO) and the oxygen level is required to ensure complete vehicle occupant comfort and safety. This paper designs an embedded system for toxic gas CO and oxygen level detection inside the vehicle cabin and to develop a sensing system using a sensor array and microcontroller.
