1. The document describes a system for desalination and water monitoring using a compact box that can fit in small spaces like homes or boats. 2. The system works by evaporating seawater using a boiler and condenser, then filtering it through a resin bed and filters to remove impurities before testing the water quality with sensors. 3. The water quality is monitored in real time using a turbidity sensor and pH sensor connected to an Arduino board. If the turbidity is below 4 NTU and pH is 7, then the water is considered safe for drinking.
