  • Abstract:
  • Incidences of Road traffic accident (RTA) have surged in recent years in spite of the sophistication and ingenuity of car manufacturers in building modern cars. This has fostered great concern for researchers to opt for better approaches to mitigate its increase. The conditions in which the driver feels most comfortable to take a nap while at the wheel are identical to the same conditions favouring mosquito attacks. Three mosquito attack conditions: low ambient temperature, low ambient light, and balancing were studied and used to design and fabricate a sleep detection device that detects sleep and alerts the driver by beep from the buzzer and vibration when sleep has been detected. The primary components used for designing the sleep detector includes: microcontroller, temperature sensor, light sensor, tilt sensor, passive buzzer, and vibration motor. The microcontroller is the brain of the device, as it processes and interprets the inputs from the sensors used and sends signals to the buzzer and the vibration motor at the incipient of sleep conditions. The device was built with a mobile app which is used to set or adjust the detector device to adapt to varying environmental conditions, displaying the ambient temperature and light intensity in real-time and records the time sleep was detected when connected. The average response rate of the device is 91% with an estimated accuracy of 67% which can be compared to its contemporaries available in the market, having response rates and accuracy ranging from 80% to 98% and 60% to 85% respectively. The device is portable, worn on the ear, and can be procured for an estimated price of N65,000 Nigerian Naira which is about $52 US dollars. The device case was modeled and printed in 3D using a 3D software and printer.
