摘要： A sun meter having a processor receiving a signal from a photocell. The processor first compares the signal to a first threshold to determine if it is daytime. If it is daytime, the processor then compares the signal to a second threshold to determine if the signal is greater than a value selected to correspond with direct sunlight. If the signal is greater than the second threshold, a counter counts. For each day of use, the amount of time of direct sun is tallied and may be displayed. An average amount of direct sun for a period of days may also be displayed. It is anticipated that a plurality of meters will be utilized in a specific area to determine the specific locations which receive the most direct sunlight and then know what plants will thrive and where to place such plants.
