Now a day many accidents are occurring due to the alcohol consumption of the driver or the person who is driving the vehicle therefore drunk driving is one of the main reasons for accidents around the world. Alcohol detector in cars is designed for the safety of people sitting inside the car. This recessed kit must be installed or installed inside the vehicle. The sensor of this kit will detect the amount of alcohol consumed by the person and will show the same by the visual indication that they are LED. The main unit of the recessed kit is an "Alcohol Sensor" if the person inside the car has consumed alcohol, then it is detected by the sensor. The sensor used for this purpose is the MQ3 alcohol sensor. The sensor is connected to the ADC0804 which is an additional interface to the 8051 microcontroller. The detected value is displayed by the number of LEDs just as the car's ignition system is switched off. The programming language used to develop the software on the microcontroller is Embedded C / Assembly. The RIDE cross-compiler is used to edit, compile, and debug this program. Flash magic programmer is used to burn code developed in RIDE on the Microcontroller Chip.
The main objective of this project is "Detection of conduction rubber". Now one day, many accidents are happening due to the alcohol consumption of the driver or the person who is driving the vehicle. Thus, driving while intoxicated is a major reason for accidents in almost every country in the world. Alcohol Detector in Car project is designed for the safety of people sitting inside the car. This project must be mounted / installed inside the vehicle. This project will detect the amount of alcohol consumed by the person and will show the same to the LCD. This product can be used to identify if person is drunk, which is used by police traffic through many countries. The main unit of this project is an "alcohol sensor". If the person inside the car has consumed alcohol, then it is detected by the sensor. The sensor used for this purpose is the MQ303A alcohol sensor. The sensor is connected to the ADC0804 which is connected to the 8051 controller. The detected value is displayed on the 16x2 LCD.
AT89s52
The 89s52 is an 8-bit microprocessor originally designed in the 80s by Intel that has gained great popularity since its introduction. Its standard form includes several standard peripherals on the chip, including timers, counters and UARTs, plus 4kbytes of program memory on the chip and 128 bytes (note: bytes, not Kbytes) of data memory, making possible singlechip implementations. Its hundreds of derivatives, manufactured by several different companies (such as Philips) include even more peripherals on the chip, such as analog-to-digital converters, pulse width modulators, I2C bus interfaces, etc. Costing only a few dollars per IC, the 8051 is estimated to be used in a large percentage of all products in the embedded system.
