Aumano: Automatic Mail Notification System Using ESP-NOW Protocol

Abstract

The invention provides a wireless mailbox notification system utilizing an ESP32-based transmitter and receiver, designed to alert users when their mailbox is accessed. The transmitter, powered by a rechargeable lithium polymer battery, includes a mercury switch that detects tilting when the mailbox is opened. The system communicates using the low-power ESP-NOW protocol, sending a signal to a receiver equipped with a visual LED indicator. The receiver is powered by a wall outlet and visually signals the user when the mailbox has been accessed. With deep sleep functionality, the system conserves battery power, allowing for up to 4 years of operation on a single charge. The system provides a simple, energy-efficient solution for mailbox monitoring, offering enhanced convenience and peace of mind for users without requiring frequent battery replacements or network setups.
