लाईट सेन्सर म्हणजे काय ? There are different types of light sensors available such as photo resistors, photodiodes, photovoltaic cells, phototubes, photomultiplier tubes, phototransistors, charge coupled devices, and so on. But, LDR (Light Dependent Resistor or photoresist or) is used as a light sensor in this light sensor circuit. These LDR sensors are passive and doesn’t produce any electrical energy. Light sensor is usually use in street light, & another use in industries, laboratory, school & collages for measuring light intensity.

लाईट सेन्सर कसा काम करतो ? When light falls on sensor it detect & we get output. And it also detect darkness when light is not detected.
