If light falling on the device is of high enough frequency, photons absorb by the semiconductor give bound electrons enough energy to jump into the conduction band. The resulting free electron (and its hole partner) conduct electricity, thus lowering resistance. LDR(Light Dependent Resistor Sensor) also known as photoresistor is a resistor whose resistance varies with the amount of light falling on it. This is a small size LDR with a size of 4mm.\u003c\/p\u003e\n\u003cp\u003eTo use, connect one side of the photocell (either one, it's symmetric) to power (for example 5V) and the other side to your microcontroller’s analog input pin. Then connect a 10K pull-down resistor from that analog pin to ground. The voltage on the pin will be 2.5V or higher when it's light out and near the ground when its dark. This sensor can be use for making a light sensor, color sensor, object sensor, line sensor, etc.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eFeatures :\u003c\/strong\u003e\u003c\/h2\u003e\n\u003col\u003e\n\u003cli\u003eSmall open frame package.\u003c\/li\u003e\n\u003cli\u003eEpoxy coated.\u003c\/li\u003e\n\u003cli\u003eMoisture resistant.\u003c\/li\u003e\n\u003cli\u003eSpectral response is similar to the human eye.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch2\u003e\u003cstrong\u003eApplications:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003col\u003e\n\u003cli\u003eCamera Exposure Control.\u003c\/li\u003e\n\u003cli\u003eAuto Slide Focus – dual cell.\u003c\/li\u003e\n\u003cli\u003ePhotocopy Machines – thickness of toner.\u003c\/li\u003e\n\u003cli\u003eColorimetric Test Equipment.\u003c\/li\u003e\n\u003cli\u003eDensitometer.\u003c\/li\u003e\n\u003cli\u003eElectronic Scales – twin cell.\u003c\/li\u003e\n\u003cli\u003eAutomatic Gain Control modulated light source.\u003c\/li\u003e\n\u003cli\u003eAutomated Rear View Mirror.\u003c\/li\u003e\n\u003cli\u003eAutomatic Headlight Dimmer.\u003c\/li\u003e\n\u003cli\u003eNight Light Control.\u003c\/li\u003e\n\u003cli\u003eOil Burner Flame Out.\u003c\/li\u003e\n\u003cli\u003eStreet Light Control.\u003c\/li\u003e\n\u003cli\u003eAbsence \/ Presence (beam breaker).\u003c\/li\u003e\n\u003cli\u003eSite Sensor.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch6\u003e\u003cspan style=\"color: #ffffff;\"\u003eAn internal link is any link from one page on your website to another page on your website.
