Automatic room power control / Maizatul Sahrina Mohd Busri and Suhaiza Mahamat

Automatic room power control is used to switch ‘ON’ and ‘OFF’ the light automatically. In this circuit we use two LDRs, which are placed one after another. So that they may separately sense the person going into or coming out of the room. The output of two LDR senses are used in conjunction with a...
