Automatic door lock and alcohol sensing alert using IOT / Muhammad Nazhan Azri Razali

Most cars these days have less safety features installed. This causes many accidents that occur such as car theft cases. Furthermore, many accidents also occur as a result of the negligence of drunk drivers. This is very worrying in terms of the safety of drivers in this country. So, Automatic Door Lock and Alcohol Sensing using IoT was created to add safety features for a car so that cases of car theft and road accidents can be reduced. This safety feature uses an Arduino UNO as a microcontroller that controls the alcohol sensing alert by detecting gas through the gas sensor and producing outputs for solenoid. While HC-05 bluetooth module becomes a microcontroller to control the smart door lock system by giving the instructions through an application on a smartphone and issuing an output to a solenoid. Through the gas sensor, users can detect the level of intoxication of a driver and can prevent the driver from driving in dangerous conditions. While through a smartphone, a vehicle owner can refuse to allow his car to be stolen. With this, cases of vehicle theft and cases of road accidents due to drunk drivers can be reduced.
