Shower Pump Controller

The project

An automated water evacuation system for my shower built with Arduino. This DIY project solves a practical problem by automatically managing water drainage using a pump controlled by a relay module. The system employs two float sensors positioned at different heights to detect water levels - one triggers the pump activation when water reaches a certain level, while the second acts as a safety mechanism to prevent overflow. LED indicators provide real-time visual feedback on the system's operational state (standby, pumping, or critical level). The code is optimized for Arduino Nano but can be easily adapted to other Arduino boards. This project demonstrates practical application of embedded systems, sensor integration, and relay control in solving real-world home automation challenges.
