This kit is being the feature of auto on of light also depends upon if the person is available in the room i.e. if the person enters the room and also the light intensity is less then only light will glow. The feature can be used in a lift in nights that is as soon as the person enters the light glows and because of counter permit a limited number of people (to remove overload).
This kit is an effort to design a prototype model to facilitate both the above features that this will count the number of people displaying the output on LCD and if the person is available in the room and light is also less than only light will turn on. The light will not turn on if no person is available
In this kit, the LDR continuously monitors the light intensity. If the intensity is less and the IR sensor at the entry gate sends a signal (which signifies a person’s entry) then a signal is sent to controller which drives to driving unit to glow the light. Besides this, the signal from IR entry increases the counter by 1 which is displayed on the LCD (signifies person’s entry). Similarly, the signal from the IR exit will decrease the counter. If the counter is zero the light will not glow.
