LDR (LIGHT DEPENDENT RESISTOR) IN PUNE Two cadmium sulphide (cds) photoconductive cells with spectral responses similar to that of the human eye. The cell resistance falls with increasing light intensity. Applications include smoke detection, automatic lighting control, batch counting and burglar alarm systems. Features- *Wide spectral response . *Low cost. *Wide ambient temperature range. LIGHT MEMORY CHARACTERISTICS: Light dependent resistors have a particular property in that they remember the lighting conditions in which they have been sorted. This memory effect can be minimised by storing the LDRs in light prior to use.Light storage reduces equilibrium time to reach steady resistance values.
