Arduino Smart Letterbox

Posted on July 15th, 2016

Never forget to collect the mail ever again with this useful Arduino mail notifier! Using 315MHz wireless radios, Riley Porter has created a system that lets you know whenever the mail arrives. With this system you never have to worry about soggy mail ever again, and can even keep track of the typical times that mail arrives in your letter box. The notifier uses a light sensor to detect when a letter has been received and then transmits a notification to the receiver over a 315MHz wireless signal. To get started on this project check out the following link.


This project would be a great addition to your existing smart home, or would be a fantastic project to start with if you are looking to add 21st century smarts to your home.

The wireless functionality in this project is based on a 315MHz wireless connection. These types of connections are very common and have the potential to be used in many different projects. If you are planning on working on this project, or any other that requires wireless communications, SuperHouse Automation recommends the Freetronics 315MHz Receiver Shield. The shield has a large, gold plated prototyping area, three status LEDs and a built in reset button. For more information visit the 315MHz Receiver Shield page.
