Abstract
Time is the most precious asset in our life. Time cannot be accumulated, nor can it be stopped. Therefore, it is important to invest our time wisely on technologies that can benefit mankind. Nowadays, our lives are getting much more challenging and complicated. Everyone demands for more time to finish their endless tasks. To allocate portion of time checking their pigeonhole (mailbox) for incoming letter become more difficult. Thus, sometimes someone might miss or some important letters that may lead to ineffectiveness. A solution to this problem is to develop a pigeonhole letter detector system. This system concentrates to reduce the time wasted on checking the letter/mail inside the mailbox and offers a better notification services to the pigeonhole’s (mailbox) owner. This system bests operate in building with various floors such as office or flat houses. The main task of the system is to inform the users using e-mail or SMS when there is a letter/mail inside their respective pigeonhole. Users only go to collect the letter from the pigeonhole after he or she received the informing email or SMS and thus avoiding extra work. This thesis presents the development and implementation of the pigeonhole letter detector system. Each pigeonhole is equipped with a sensor to detect the present of letter. A microcontroller is used to monitor the sensors status and to communicate with the computer system developed in VB.NET. The computer system will process the data and send notification in SMS/email to the user.
