Abstract

An automatic system for monitoring chemistry information for a body of water comprises a sensor for determining chemistry information, a microprocessor for processing chemistry information, and a housing coupled to at least one of the sensor and the microprocessor. Preferably the housing is floatable or mountable. The method of providing chemistry information of a body of water comprising the steps of obtaining a sample of the body of water and determining chemistry information.

Claims

1. An automatic system for monitoring chemistry information for a body of water, comprising:

a. a housing;

b. at least one sensor coupled to the housing, the at least one sensor configured to determine chemistry information for the body of water; and

c. a control circuit coupled to the at least one sensor, the control circuit is programmable with at least one acceptable threshold level of chemical composition for the body of water, wherein the system is configured to suggest the at least one acceptable threshold level specifically for the body of water in response to a parameter of a volume and a type of the body of water entered.

2. The automatic system of claim 1, wherein the control circuit compares the chemistry information determined by the at least one sensor to a programmable threshold.

3. The automatic system of claim 2, wherein the threshold represents an acceptable minimum value or maximum value of the chemistry information for the body of the water.

4. The automatic system of claim 1, wherein the chemistry information monitored by the system comprises one of at least one alkalinity, pH level, temperature, calcium hardness, total hardness, dissolved solids, and a sanitizer of the body of water and a combination of at least two thereof.

5. The automatic system of claim 4, wherein the sanitizer is one of chlorine or bromine.

6. The automatic system of claim 1, wherein the system is configured to monitor the chemistry information for the body of water continually while the system is powered on.

7. The automatic system of claim 1, wherein the system further comprises a timer coupled to at least one of the at least one sensor, the control circuit, and the housing.

8. The automatic system of claim 7, wherein the timer is configured to provide a time stamp to the at least one sensor while the at least one sensor determines the chemistry information for the body of water.

9. The automatic system of claim 8, wherein the time stamp and the chemistry information are transmitted to the control circuit.

10. The automatic system of claim 1, wherein the system further comprises a chemistry display panel coupled to the at least one sensor.

11. The automatic system of claim 10, wherein the at least one sensor is configured to communicate the chemistry information to the chemistry display panel during a programmable time interval.

12. The automatic system of claim 10, wherein the chemistry display panel further comprises an indicator configured to indicate a status of the body of water based on the chemistry information processed by the control circuit.

13. The automatic system of claim 12, wherein the indicator is one of a green light indicator for a safe status for the body of water, a yellow light indicator for a cautionary status for the body of water, and a red light indicator for an unsafe status for the body of water.

14. The automatic system of claim 12, wherein the indicator is configured to be audible.

15. The automatic system of claim 1, wherein the at least one sensor is configured to communicate the chemistry information to a remote location.

16. The automatic system of claim 15, wherein the remote location is one of a personal digital assistant (PDA), a custom sign, a computer, a satellite, a wireless device, a phone, a USB port, a pager, and a device configured to add chemicals to the body of water.

17. The automatic system of claim 15, wherein the at least one sensor is configured to communicate the chemistry information to the remote location through at least one of a wireless connection, a cellular connection, a wired connection, an optical connection, an infrared connection, and a custom radio interface connection.

18. The automatic system of claim 1, wherein the system further comprises an antenna coupled to the housing and configured to transmit and receive radio waves.

19. The automatic system of claim 1, the system further comprising a pump system for collecting a sample of the body of water.

20. The automatic system of claim 1, the system further comprising a safety element configured for indicating when the body of water is unsafe.

21. The automatic system of claim 1, wherein the system is at least one of mountable and floatable.

22. The automatic system of claim 1, wherein the system is configured to be tethered.

23. The automatic system of claim 1, wherein the system is further configured to selectively float to at least one predetermined water depth measured from the surface of the body of water.

24. The automatic system of claim 1, wherein the system further comprises an actuator to relocate the system to at least one predetermined location of the body of water.
