        LDR or light dependent resistor is widely used in electronic sensor circuit. The resistance of sensor changes as the intensity of light changes. This a passive sensor and needs a  drive to get the variation of light intensity in terms of voltage or current. A simple, low cost sensor is best solution for most of project. The performance of the LDR is the major issue in selection of sensor.

         A typical light sensor is designed using LDR as shown in figure. The range of vout can be adjusted with limiting resistor used in the circuit.
