Low-Cost Wireless High Water Detection System

By Chen-hang (Michael) Yen


This design project aims to create an inexpensive flood detection system to monitor rising water in remote locations or residential areas.
The high water detection system divides into two parts: water sensing unit and data display unit.
Both subsystems are based on the ATmega 328P microcontroller and they are communicating wirelessly
via radio frequency (RF) transceivers. Additionally, several custom-built modules, including water sensors,
charging regulator, and status board, are designed to support moisture detection, power management, and information display.
