Abstract

A notification system for incoming letter in the letter box is very important especially for tall building residents and offices. By using this system, the user can do more efficient mail checking by relying on the notification from the system. The objective of this project is to develop an intelligent mail notification system that capable to alert the user whenever there are incoming letters in the letter box through Short Message Services (SMS). The designed system consists of an infra-red (IR) sensor, a microcontroller and a transceiver. We use an Arduino Uno board as the microcontroller and a GSM module as the transceiver. When the IR sensor senses a letter, it will trigger the microcontroller to send a command to GSM module for sending a notification message to the predetermined phone number. We evaluate the performance of the designed system by measuring the distance of the letter in which the IR sensor can detect. The result shows that the IR sensor effectively detects the letter up to the distance of 15 sentimeters which is equivalent to the letter box height. In addition, we also tested the detection of two different letter sizes which are A4 size and envelope size. The result shows that our system can detect both sizes of letter.
