Abstract
The overall purpose of the design is to identify when mail is placed in a mailbox, and transmit a signal to a personal device notifying the user that mail has been delivered. The design will use an Arduino motion sensor to detect the placement of mail. The detection signal from the motion sensor will be processed by the Arduino R4 board along with the Arduino IoT software. The output of this process will be relayed to the users personal device over a Wi-Fi connection. This device will make an easy to use mail detection system.
