Abstract
A pool or spa control system includes a sensor system with one or more sensors in contact with a main body of water. The sensor system measures water condition data of the body of water and is mounted on a wall submerged in the main body of water. The pool or spa control system also includes a modem that facilitates data communications between the sensor system and communication equipment positioned at a different location from the main body of water.
Claims22
A pool or spa control system, comprising:
- a sensor system comprising one or more sensors in contact with a main body of water, wherein the sensor system is configured to measure water condition data of the body of water, and wherein the sensor system is mounted on a wall submerged in the main body of water;
- and
- a modem configured to facilitate data communications between the sensor system and communication equipment positioned at a different location from the main body of water.
A sensor system, comprising:
- a housing comprising a first inductive coupling that is electrically coupled to a power line, wherein the power line is configured to enable transmission of electrical power from a transformer to the first inductive coupling and data communications from a modem to the first inductive coupling using a power-line communication protocol;
- and
- a cartridge comprising a second inductive coupling and a first sensor, wherein the cartridge is configured to receive the electrical power and the data communications at the second inductive coupling from the first inductive coupling.
A method for controlling a sensor system, comprising:
- transmitting electrical power from a transformer to a sensor along a power line, wherein the sensor is in contact with a body of water;
- transmitting data communications from a modem to the sensor along the power line using a power-line communication protocol;
- and
- receiving sensor readings of the sensor at the modem from the power line.
A sensor system for a swimming pool or spa that communicates with a lighting system or a sensor system using a power-line communication technique.
A pool or spa control system, comprising:
- a sensor system located in or adjacent a main body of water and having wired electrical connections with a transformer and a modem assembly.
