Automatic Drunken drive prevention System

SKU: 010045



Driving while either intoxicated or drunk is dangerous and drivers with high blood alcohol content(BAC) are at increased risk of car accidents, highway injuries and vehicular deaths.Prevention measures evaluated include license suspension or revocation, impounding or confiscating vehicle plates, enforcing open container bans, increasing fine penalties, jail, mandating education for youth and lowering legal BAC’s. Even though these much hurdles created by authorities to drunken drive, it is still continuing like serial episodes.As such there is no effective mechanism to prevent this. Here, we have planned to design an Automatic Alcohol Detector, which is integrated with the steering wheel. Ethanol has more capacity to absorb IR rays. So,we use an IR Sensor which is mounted on steering.An IR source led-894 directs IR Energy through the sensor continuously. If the flow of IR rays is interrupted by absorption of alcohol vapour a relay circuit is activated.This relay circuit has control over the fuel supply system and it cuts-off the fuel supply to the engine.This makes the car to come to halt slowly .The higher the concentration of ethanol, the more infrared absorption occurs (same way that a Coolers absorbs visible light, alcohol absorbs infrared light).
