In the days of technology postman still comes to our house for delivering the letters, couriers and parcels. Because some things like courier, parcels can’t sends via email and by using any other electronic media. So for getting notification of our letter delivery in our mail box here we design an intelligent mail/letter box,which provides notification of delivery of letters in our mail box via message to our mobile phones.In this system an IR pair is used for sensing incoming letter in mail box and a GSM module for sending message to our phone. And a 16x2 LCD display for displaying time and letter box status (empty or not), delivery time, date and a real time clock circuit also is used in this system
