Often than not, most would depend on artificial lights such as the room lamps and computer lights. The issue here is that natural lighting are not used since students depends on artificial lights, so curtains usually remain closed for long hours which is not a healthy lifestyle. Our objective is to prevent and to alert the students on the time it was at that time. Our second objective is to instill healthy lifestyle habits in student's life. Our third objective is to make an automatic curtain which opens and closes following the surrounding brightness. This project is based on the theme of 3R (Reduce, Reuse, and Recycle). This work allows easy maneuver for opening curtains using light sensors while reusing and recycling old boxes and CD's to create a DIY item. In this prototype, the system will start when the sensor detects illumination of light depending on the time of the day. Using combination of software and hardware designing, a prototype was created and tested. Based on the result findings, the error finding between our expectation and real result is 2% error. The sensitivity of photo resistor sensor had the sensitivity of 14Ω/nm during daytime, while 55Ω/nm during nighttime. The accuracy of sensor is about 95% for both during light and dark.
