Alcohol Detection and Vehicle Control with SMS Monitoring

Why Alcohol Detection??

    Nowadays so many peoples are doing drink and drive. Hereby so many accidents are occurs. To prevent this we are making some techniques using alcohol sensor and also we are tracking by sms. We will see about this in detail in this blog.

Proteus Simulation

Hardware Prototype

 

In this project we are using Arduino uno to control the motor and to send alert message. It contains two push buttons to start and stop the motor. If we press start button, Arduino will give high output to relay and while if we press start button, Arduino will give low output to relay. Two transformers are used, first transformer is used to give power supply to motor and second transformer is used to give power supply to Arduino, GSM and LCD. 16x2 LCD is used to display the alcohol percentage. MQ sensor is used for alcohol sensing. SIM800C is used for sending alert message.

After powering up the project, alcohol percentage appears in LCD. Arduino takes some time initialize the GSM. Initially it shows 18% alcohol. When we the alcohol on the side near sensor, the alcohol percentage starts increasing slowly in LCD. After reaching the limit (50%), the motor will stop and we will receive the alert message to a mobile. it was clearly explained in the video.
