Anti-sleep alarm with Driver Safety system using Arduino Nano

Driver fatigue remains a leading cause of road accidents worldwide, consequently contributing to significant fatalities and injuries each year. To address this critical safety challenge, we present an innovative Anti-Sleep Alarm System built around Arduino Nano technology. Specifically, this advanced system continuously monitors driver alertness through an IR sensor-based eye blink monitor that precisely tracks blink patterns and eye closure duration in real-time.

Moreover, the system’s core intelligence lies in its sophisticated algorithm that analyzes eye movements to detect early signs of drowsiness, including prolonged eye closure and abnormal blink frequency. When fatigue thresholds are exceeded, the system immediately triggers a multi-stage safety response: for instance, an audible buzzer alarm provides immediate auditory warning, while a bright red LED delivers visual alert, and the integrated 5V relay module can interface with vehicle systems for enhanced safety measures.

Furthermore, engineered with precision on a custom PCB board, the system offers flexible power options through a 9V battery for portability as well as a 9V SMPS for stationary testing. Additionally, components such as BO motors with wheels demonstrate the system’s capability for integrated vehicle control. Ultimately, this comprehensive driver safety solution represents a significant step forward in accident prevention technology, thereby providing reliable drowsiness detection to ensure safer journeys for all road users.
