Abstract

The handheld data-logging spray apparatus incorporates a global positioning system (GPS) receiver and microcontroller into a conventional handheld spray unit. As an operator dispenses a chemical using the handheld data-logging spray apparatus, the microcontroller records (among other things) the volume of chemical dispensed and the GPS location of the sprayer. The recorded data is processed and stored on a removable USB thumb drive. The operator can download the data from the thumb drive and manipulate the data using a conventional spreadsheet program or a commercially-available geographic information system program.

Claims

1. A handheld data-logging spray apparatus comprising:

a spray delivery assembly comprising a handheld liquid reservoir bottle and a finger-pumpable trigger;

a microcontroller;

a flow measurement means; and

a geographic information system receiver;

whereby the handheld data-logging spray apparatus is structured so that as an operator uses his fingers to pump the trigger of the apparatus, the microcontroller records an amount of a liquid dispensed from the handheld liquid reservoir bottle through the apparatus, and simultaneously records a geographic location of the apparatus.

2. The apparatus of claim 1 wherein the geographic information system receiver comprises a global positioning system (GPS) receiver, the microcontroller and the GPS receiver being housed within a control housing adjacent the finger-pumpable trigger, the GPS and the microcontroller comprising a data integration module.

3. The apparatus of claim 2 wherein the data integration module further comprises a data storage interface port and a mobile data storage medium.

4. The apparatus of claim 3 wherein the storage interface port comprises a USB port and the mobile data storage medium comprises a USB flash drive.

5. The apparatus of claim 2 wherein the apparatus is structured so that, an amount of liquid dispensed from the handheld liquid reservoir bottle, and a geographic location of the handheld data-logging spray apparatus are recorded as periodically occurring waypoints, each waypoint further comprising a number of satellites engaged by a GPS recorder and a projected GPS error.

6. The apparatus of claim 5 wherein each waypoint further comprises a user-selected variable(s), the user-selected variable(s) being designated by a position of a selection knob.

7. The apparatus of claim 2 wherein the flow measurement means comprises a flow measurement means generating an electrical signal, the electrical signal being directed to the microcontroller.

8. The apparatus of claim 7 wherein the flow measurement means is positioned in a flow measurement chamber, the flow measurement means measuring an amount of liquid pumped (via the finger-pumpable trigger) from the handheld liquid reservoir bottle and through the flow measurement chamber.

9. The apparatus of claim 8 wherein the flow measurement chamber abuts the control housing.

10. The apparatus of claim 7 wherein the flow measurement means comprises a pinwheel device.

11. The apparatus of claim 1 wherein a liquid flow volume is deduced based on an amount of time that liquid flows from the handheld liquid reservoir bottle and through the handheld data-logging spray apparatus.

12. The apparatus of claim 1 wherein the spray delivery assembly comprises a sprayer hand grip, and nozzle so that, when the trigger is pumped, a liquid is pumped up from the handheld liquid reservoir bottle, the liquid is directed through the sprayer hand grip and nozzle, thereby dispensing the liquid.

13. A method of spraying and thereby treating plants and recording data documenting the spray treatment;

the steps of the method comprising;

(a) providing the handheld data-logging spray apparatus of claim 1;

(b) connecting a portion of the spray delivery assembly to a handheld liquid reservoir bottle containing a liquid;

(c) spraying target plants with the liquid by pumping a trigger on the handheld data-logging spray apparatus; and

,

(d) during step (c), recording waypoint information on a data storage means.

14. The method of claim 13 wherein, in step (d), the waypoint information comprises at least time, geographic location, and volume of the liquid dispensed by the handheld data-logging spray apparatus.

15. The method of claim 13 further comprising:

(e) downloading waypoint data from the data storage means to a computer.

16. The method of claim 15 wherein the waypoint data is in a spread sheet format.

17. The method of claim 13 wherein the liquid comprises a non-water liquid.

18. A method of making a handheld data-logging spray apparatus, the method comprising the steps of:

(a) providing a microcontroller, the microcontroller comprising a programmable data processing data recorder;

(b) connecting the microcontroller to a geographic information system;

(c) integrating the microcontroller and geographic information system into a control housing to create a data integration module, the data integration module being capable of operating as a handheld component; and

(d) connecting the data integration module to a handheld spray assembly;

(e) connecting a flow measurement module to the data integration module and the spray assembly so that the flow measurement module provides an electrical flow volume signal to the microcontroller as a liquid is pumped from a handheld liquid reservoir bottle and through the handheld spray assembly and out of a spray assembly nozzle when a finger-pumpable trigger is pumped.

19. The method of claim 18 further comprising:

(f) programming the microcontroller so that the microcontroller records sequential waypoints, each waypoint comprising at least a time, geographic location, and an amount of a liquid that is dispensed from the handheld data-logging spray apparatus.
