Photoresistor in 60s ⚡
*Photoresistor:*
A photoresistor, also known as a light-dependent resistor (LDR), is a passive electronic component whose resistance changes in response to incident light intensity. It consists of a semiconductor material that exhibits a decrease in resistance as the light intensity increases and vice versa.
Application:
Photoresistors are commonly used in light detection and sensing applications.
They find applications in automatic lighting systems, streetlights, camera exposure control, and burglar alarm systems. By measuring the resistance of the photoresistor, the intensity of light in the surrounding environment can be determined, allowing for automatic adjustments or triggering of various electronic circuits.
