when there is low amount of light the light automatically glows and when there is sufficient amount of light it automatically turns off the light. here based on our room condition the threshold value we took is 100 for the ldr sensor. when we place a hand on ldr(not allowing any light on ldr) arduino automatically turns on the led.
switching of the street lights becomes an easy task. we can choose our pre programmed schedules; plan a schedule of our own to manage every street lamp, automatically according to our needs , . when the street lighting needs to decrease in a certain area or within a certain time span, this system helps to dim the lights accordingly.
