Let us introduce Smart Mail Box

As we know technology has became so advanced that we have almost stopped writing letters, but still we have mail boxes as there are few letters that drop into our mail boxes.

So, the technology has made us lazy and hence tend to forget to check our mail boxes for the letters that drop into our mail box as we don’t remember. Thus, this smart mail box will notify whenever there is a letter in your mail box. This notifies you using the GSM module and the ir sensor that senses the letter in you mail box, and then with the help of arduino using the GSM module it notifies the user about the letter in their mail box.
