Description
5mm Light Dependent Resistor LDR Sensor changes resistance with the change in the ambient light exposure on the surface of the sensor. 5mm LDR Sensor (Light Dependent Resistor) is a type of photocell which finds excellent use in light sensing device application, whether it is automatic outdoor light ON/OFF switch or Indoor automatic light switch. The sensor works best in both Light and dark region.
Two Cadmium Sulphide (CDs) PhotoConductive Cells with spectral responses similar to that of the human eye. Cell resistance falls with increasing light intensity. An application includes smoke detection, Automatic lighting control, batch counting and burglar alarm systems.
