Web26 nov. 2024 · November 26, 2024. Light-dependent resistors also known as LDRs, or photoresistors are electronic components used to detect light and change the operation of a circuit dependent upon the light levels. Light-dependent resistors are often used in electronic circuit design, where the presence or level of light needs to be detected. WebThe LDR[edit edit source] A light dependent resistor is a resistor whose resistance depends on the amount of light shining on it. Its resistance gets less the more light shines on it. It can be used in circuits that are light dependent. For example, switching circuits for street lights. The ambient light gets too low; the lamp turns on.
