Abstract

A data logger system utilizing a censor which obtain a plurality of measurements of an environmental parameter and generates a plurality of signals representing such measurements. A processor receives the plurality of signals and produces a table of counts in sequential format. An external prime converter receives the table of sequential counts and converts the same to human readable values representing the environmental parameter measurement.

Claims

1. A system for gathering and presenting environmental data comprising:

a a sensor, said sensor obtaining a plurality of measurements of an environmental of parameter and generating a plurality of signals representative of said measurements;

b a processor, said processor receiving said plurality of signals and producing a plurality of counts said processor storing said plurality of counts to produce a table of sequential counts; and

c an external prime converter, said external prime converter receiving said table of sequential counts from said processor and converting said table of sequential counts to a sequential set of human readable values.

2. The system of claim 1 which said processor additionally comprises an analog-to-digital converter receiving said plurality of sensor signals.

3. The system of claim 2 in which said plurality of sensor signal comprises values of electrical resistance.

4. The system of claim 1 in which said processor comprises at least a portion of a microprocessor control unit.

5. The system of claim 4 which said processor additionally comprises an analog-to-digital converter receiving said plurality of sensor signals.

6. The system of claim 5 in which said plurality of sensor signal comprises values of electrical resistance.

7. The system of claim 4 in which said processor comprises at least a portion of a microprocessor control unit.

8. The system of claim 7 in which said plurality of sensor signal comprises values of electrical resistance.

9. The system of claim 4 in which said processor further comprises an electronically erasable programmable read only memory unit.

10. The system of claim 9 which said processor additionally comprises an analog-to-digital converter receiving said plurality of sensor signals.

11. The system of claim 10 in which said plurality of sensor signal comprises values of electrical resistance.

12. The system of claim 9 in which said processor comprises at least a portion of a microprocessor control unit.

13. The system of claim 12 in which said plurality of sensor signal comprises values of electrical resistance.
