Arduino Based Mail Notifier System

IOT

Physical Mail or Post is a method of transporting documents, packages, cards, parcels and letters. This service is usually done by a postal service system. Mail is usually delivered by mail man post man to our homes. We get important documents like bills, invitations, bank statements etc. in mail.If we don’t check our mail box regularly, we might miss the deadlines for payment of bills etc. It is a tedious job to regularly check for mail as mail boxes are often placed outside the house or in some cases, a common place at the end of the street.In this project, a simple mail alert system is developed using simple and cheap wireless communication devices. The aim of the project is to notify the user with a message whenever he/she receives a mail in their mailbox. The main sensor used for detecting the mail is the photo resistor or LDR. Majority of mailboxes are open and shut type i.e. a small door must be opened and the mail must be placed inside the box.If we place the LDR on the inside of that small door, it receives light only when the door is opened to insert a mail. As the LDR senses the changes in the ambient lighting (by changing its resistance accordingly), it can differentiate between a door – open scenario and a door – close scenario.
