Lights & LED Circuits & Schematics LDR

An ordinary automatic room power control circuit has only one light sensor. The circuit uses two LDRs which are placed one after another (separated by a distance of say half a metre) so that they may separately sense a person going into the room or coming out of the room. Outputs of the two LDR […]
