LDR AS OPTICAL SENSOR Objectives of this experiment: In this trainer you will study that LDR resistance changes in proportion to light intensity. This causes a corresponding change in the voltage divider output Vout is given by Built in regulated power supply: +(0-16)VDC/300mA Input Supply: 230 VAC/50Hz mains operated. Dimension: 27cms x 17cms x 10cms. Weight: 500gms Qty :
