Apparatus and method for use in determining conditions related to a plant
First Claim
1. An apparatus for determining the conditions related to a plant comprising:
- a first sensing means for generating a first electrical signal corresponding to a first condition related to said plant;
a second sensing means for generating a second electrical signal corresponding to a second condition related to said plant;
an indication means comprising a common galvanic meter;
a coupling means for selectively coupling said first and second signals to said galvanic meter, whereby said galvanic meter is made selectively responsive to said first and second signals and selectively converts said first and second signals into indications of said first and second conditions, respectively;
a first reference source for relating said indication of said first condition to a first preselected reference for said first condition;
and a second reference source for relating said indication of said second condition to second preselected reference for said second condition.

Abstract
A method and apparatus for use in detecting conditions related to a plant are disclosed. More particularly, in accord with the invention, in the method and apparatus are provided a first sensing means for generating an electrical signal corresponding to the light level in the area surrounding a plant, an indication means comprising a meter for providing an indication or reading corresponding to the electrical signal generated by the sensing means, and a reference source in the form of a chart or table for relating the aforesaid indication or reading to a preselected reading associated with the particular plant.
In a further aspect of the invention, a second sensing means is additionally provided for sensing another condition of the plant and a coupling means is provided for selectively coupling the first and second sensing means to the meter of the indication means. Moreover, in this form of the invention, a second reference source is provided for presenting reference readings corresponding to the condition being sensed by the second sensing means.
Also disclosed is a housing for the apparatus which is designed to have storage capabilities and to permit easy use thereof.

12. A method for determining conditions related to a plant comprising the steps of:
placing adjacent said plant one of first and second sensing means, said first and second sensing means when placed adjacent said plant generating respective first and second electrical signals corresponding to first and second conditions related to said plant;
selectively connecting said first and second sensing means to a common galvanic meter of an indication means for converting said first signal to an indication of said first condition when said first sensing means is connected to said galvanic meter and for converting said second signal to an indication of said second condition when said second sensing means is connected to said galvanic meter; and
comparing said indication to a first reference corresponding to a preselected reference for said first condition when said indication is generated by converting said first signal and to a second reference corresponding to a preselected reference for said second condition when said indication is generated by converting said second signal.

13. A method in accordance with claim 17 in which:
-
said first condition is the level of light in the vicinity of said plant; and said second condition is the amount of water in the soil of said plant.
