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.

Abstract: In one embodiment, a wireless measurement device is provided. A wireless transceiver is configured to communicate with a base station through a wireless medium to receive configuration information. The wireless transceiver outputs a signal for use in measuring a potential or current based on the configuration information. A circuit is configured to function as a galvanostat and can receive the signal and achieve a desired current using the signal. A potential of a test cell is then measurable using the current. Also, the circuit is configured to function as a potentiostat and can achieve a desired potential using the signal. The current of the test cell is then measurable using the potential. The wireless transceiver transmits the measured potential or current wirelessly to a second wireless transceiver.
