Sleepy jacket or Sleepy Reminding Jacket they make is designed for driving safety standards. How it works jacket reminds the sleepy rider by giving vibration to the body of the rider. In this jacket implanted four main components of the Earclip Hearth Rate Sensor as input, Arduino Uno R3 as a microcontroller, 5.9 Volt DC motor as output and PCB board. The system they create can vibrate DC motors if the detectable pulse rate is below normal or less than 60 mmHg and returns to rest if the pulse reaches a normal value or about 80 mmHg. To use the jacket is also quite easy The earclip sensor is installed in the ear, then the switch on the jacket is turned on, the system will detect the pulse and get the average pulse rate per 20 seconds, vibration arises when the pulse is smaller than 60 mmHg (Sleepy condition) if the pulse is normal then this vibration stops automatically
