APPLICATION OF RASPBERRY PI BASED EMBEDDED SYSTEM FOR REAL TIME PROTECTION AGAINST ROAD ACCIDENTS DUE TO DRIVER’S DROWSINESS AND/OR DRUNK AND DRIVE CASES

Present work deals with the application of raspberry pi CPU based sensing system to the detection of driver’s lethargy and alcoholism in order to avoid the road accidents. The embedded system consists of 5 megapixel digital camera, alcohole detection sensor and the buzzeer interfaced to the microcontroller. The embedded system is controlled by Raspbian operating system. The system detects real time situation of the driver’s vigilance and control over the vehicle. If alcoholic and / or drowsiness tests are positive, it (i) switches on the alarm, (ii) turn off the vehicle’s engine via microcontroller based program controlling ignition power source and (iii) sends a sms to the person close to the driver’s locatio
