WebThe construction of an LDR includes a light-sensitive material that is placed on an insulating substrate like ceramic. The material is placed in a zigzag shape in order to get the required power rating and resistance. The area of zigzag separates the metal-placed areas into two regions. Light Dependent Resistor Construction WebAn LDR is made of an N-type semiconductor material that is sensitive to light and possesses less or no free electrons in no light conductions such as cadmium selenide CdSe or cadmium sulfide CdS. It has very high resistance in the range of mega Ohms under no light conditions.
WebA light-dependent resistor (LDR) or photoresistor is made of a photosensitive semiconductor that’s conductivity changes when exposed to the light. ... Although an LDR is tuned to the visible spectrum of light, photodiodes are sensitive to both visible and infra-red lights. The biggest disadvantage of photodiodes is that their reverse leakage ... WebFeb 24, 2012 · A Light Dependent Resistor (also known as a photoresistor or LDR) is a device whose resistivity is a function of the incident electromagnetic radiation. Hence, they are light-sensitive devices. They are also called as photoconductors, photoconductive cells or simply photocells. They are made up of semiconductor materials that have high …
WebA photoresistor—sometimes called a photocell or light-dependent resistor (LDR)—varies its resistance in response to light. They are small, inexpensive, and easy-to-use. Consequently, photoresistors are popular in children’s toys (see example below), nightlights, clock radios, and other inexpensive gadgets. However, they are not ...
