1. A sunlight measuring device comprising:
- a sunlight measurement means for sensing incoming light at a particular site over a period of time and converting said incoming light to an electronic signal;
a microprocessor that receives said electronic signal, determines a magnitude of said electronic signal and an accumulated light value over said period of time, and compares said accumulated light value to threshold values;
a plurality of light condition indicators, each single light condition indicator corresponding to a particular one of said light thresholds; and
a power supply;
wherein, when said accumulated light value reaches one of said threshold values, said microprocessor causes a corresponding one of said single light condition indicators to be illuminated; and
wherein said illuminated light condition indicator indicates a light condition that corresponds to one of several light conditions, said several light conditions being defined in terms that include a full sun condition and a full shade condition.

Abstract
A sunlight measuring device that quantifies the accumulation of light at a particular site. The sunlight measuring device is a battery-operated device mounted on a stake for easy insertion into the ground. The device is placed at the intended site for growing a plant. The light that falls on the sunlight measuring device over a period of time is accumulated and the light accumulation is represented by a visual signal that indicates one of four light conditions: full sun, partial sun, partial shade, full shade.
