Abstract
A water monitoring device monitors and maintains swimming pool chemistry. The device includes sensors that detect water chemistry. The water monitoring device can communicate with computers and servers. This system can be used to determine if corrections to the water chemistry are required to maintain water sanitation. The device can monitor: pH, air temperature, water temperature, free chlorine levels, oxidation reduction potential, alkalinity, oxygen demand, water movement and velocity, and electrical conductivity.
