Abstract

An apparatus for monitoring and controlling a hydroponic installation which measures various sensors, controls electrical devices, and provides a rich user interface through a standard web browser accessible anywhere on the Internet. Network connectivity allows the operator to manage the system remotely, as well as view recent and historical data through web pages. Digital cameras, of the kind typically used with PCs, provide visual feedback. The apparatus can notify the operator in the case of certain predetermined conditions, using a variety of messaging methods, including email, SMS or MMS page. The operator can remotely initiate control through reply messages. An industry-standard expansion bus provides the ability to attach external devices for additional functionality. Network access can be provided by Ethernet, Wi-Fi, or a nearby cell phone with Bluetooth.

Claims

1. An apparatus for monitoring and controlling hydroponic cultivation, comprising:

A means of measuring nutrient parameters such as concentration, pH, and temperature;

A means of controlling electrical devices, actuators, valves, or pumps by means of switching a source of electrical power on and off,

A means of connecting to a computer data network and transferring data over this network to and from other computer systems;

A means of providing a user interface accessible via a world-wide-web browser software program communicating over the computer data network;

A means of allowing the operator to observe present and past measured parameters via said user interface;

A means of allowing the operator to direct the control of said electrical devices via said user interface;

2. The apparatus of claim 1, where the computer data network is the global Internet.

3. The apparatus of claim 1, where the computer data network is a digital cell phone network.

4. The apparatus of claim 1, further comprising a means of measuring the depth of nutrient solution in the reservoir or root zone.

5. The apparatus of claim 1, further comprising a means of connecting one or more digital cameras to the apparatus, to be viewed via said user interface.

6. The apparatus of claim 1, further comprising a means of measuring the amount of electrical power consumed by the apparatus itself, and by the devices for which it is controlling electrical power.

7. The apparatus of claim 1, further comprising a means of sending a notification message to the operator of the apparatus, using said computer data network.

8. The apparatus of claim 7, where the notification method is email.

9. The apparatus of claim 7, where the notification method is short message service (SMS) or multimedia message service (MMS).

10. The apparatus of claim 7 where the apparatus can receive instructions in a reply message sent by the operator in response to the notification message, and act on said instructions.

11. The apparatus of claim 7, where the notification is sent whenever any of said measured parameters are outside of a range specified by the operator;

12. The apparatus of claim 1, where the electrical power is switched using a predetermined time scheduled.

13. The apparatus of claim 1, where the electrical power is switched in response to changes in nutrient conditions.

14. The apparatus of claim 1, where the electrical power is switched in response to changes in one or more environmental conditions of air temperature, relative humidity, light intensity, carbon dioxide concentration.

15. The apparatus of claim 1, where the means of connecting to the computer data network is Ethernet.

16. The apparatus of claim 1, where the means of connecting to the computer data network is Wireless Fidelity (Wi-Fi).

17. The apparatus of claim 1, where the means of connecting to the computer data network is Bluetooth.

18. The apparatus of claim 1, where the means of connecting to the computer data network is through an AC mains based networking protocol.

19. The apparatus of claim 1, where the user interface is protected by an authentication mechanism to permit only authorized users to access the system.

20. The apparatus of claim 1, further comprising a means of storing said measurements to a memory device for later presentation to the operator;

21. The apparatus of claim 1, further comprising a means of connecting external electronic devices to the apparatus, through an expansion bus.

22. The apparatus of claim 21, where the expansion bus is Universal Serial Bus (USB).

23. The apparatus of claim 21, where the expansion bus is IEEE-1394.

24. The apparatus of claim 21, where the expansion bus is Secure Digital Input Output (SDIO).

25. The apparatus of claim 1, where the means of controlling electrical devices include the use of industry-standard X-10 automation modules.

26. The apparatus of claim 1, further comprising a means of registering the network address of the apparatus in a way that makes it accessible to said web-browser through the use of an Internet URL that is not limited to IP address, and remains fixed even if the IP address changes.

27. The apparatus of claim 1, further comprising a means of retrieving information from the Internet and using said information to modify the content displayed on said user interface.

28. The apparatus of claim 1, further comprising a means of retrieving information from the Internet and using said information to modify the control of said electrical devices.

29. The apparatus of claim 1, further comprising a means for the operator to insert comments or annotations to be recorded and stored for later observation.

30. The apparatus of claim 29 where said comments are associated with measurements taken at the time they are entered and stored along with said comments.
