Abstract:

Oversleeping is one of the most common problems that usually caused people to be late for their meetings, appointments and such. This usually happens when people set the alarm but still unable to wake up at desired time neither because they unconsciously shut off the alarm nor unable to hear the alarm rings. This designed alarm clock is capable of determining whether the user is off of the bed already by integrating the alarm itself with the sensor pad. The timeframe of alarm was manipulated also from a normal time of 2–5 minutes to 30 minutes to effectively wake up those that in deep sleep. Snooze function was also removed and it can only be turned off by moving out of the bed. The alarm was tested in accordance to the objectives of the project for 30 trials with one (1) hour interval per trial. Testing included the alarm for letting the user off the bed first before turning off, the relay for turning on and off fan and light when the alarm is on, and the sensor pad itself. The calculated z-score of the testing was 5.47723 and this was compared to the z-score given at 95% confidence level. This calculated z-score is not less than -1.645 which is the critical region. This concludes that each testing was significant and successful. The functionality of the alarm clock was improved and the objective of waking up the user before turning the alarm off, turning on and off the light and fan, respectively as long as the alarm is on were met.
