AUTOMATIC ROOM LIGHT ON / OFF WITH THE PRESENCE OF HUMAN

[raju k]

CAN ANY ONE GIVE ME SOME IDEAS REGARDING “AUTOMATIC ROOM LIGHT CONTROL WITH THE PRESENCE OF HUMAN BEING” USING 8051 uC?

 

 

WHICH SENSOR IS  USEFUL FOR THIS PROJECT?

Hi Raju,

 

Sensing the rapid change in temperature of the room is the best way I think. So try to use good quality temperature sensor.

Do some research if it is possible to sense the increase in rate of CO2, and hence sense the presence of large sized living things entered into the room.

can we use PIR SENSOR

hi one can also use pir motion sensor but it is very sensitive and needs bootup time for about 1 mnut when pwr up.

Hi Raju,

PIR is a motion sensor only. You can consider that also if it fits your implementation requirements.

hi . f there is any other way to find presance of human body in room via temperature monitoring please let us know

hallo,

according to me for motion detection PIR sensor would be the best option..

check out the following link

this will give you good idea bout working and interfacing of PIR..
