Method and system for simulating the solar cycle

摘要

A system for simulating the lighting cycle of the sun obtains a set of inflection points on a solar lighting cycle and also obtains the annual minimum sunlight value for a location at a predetermined latitude; reconstructs the daily and yearly solar cycle based about the set of inflection point and the minimum yearly value; determines the lighting period based upon the daily and yearly cycles; activates a lighting device for the determined lighting period; transmits a series of electrical pulses to the soil and receives a return signal from the soil, the return signal indicative of the conductivity of the soil; determines whether the conductivity indicates whether the soil has an adequate moisture level; and activates an LED to indicate the soil does not have an adequate moisture level.
