Light Sensitive Photo Resistor
$0.55The Light Sensitive Photo Resistor, also known as a photoresistor or light-dependent resistor (LDR), is a passive electronic component that changes its resistance based on the amount of light that falls on it. Photo resistors are used in a variety of applications, including light-activated switches, automatic street lights, and light-sensitive security systems. The photoresistor is made of a material that changes its electrical resistance when exposed to light. When the photoresistor is in the dark, its resistance is high, and when it is exposed to light, its resistance decreases. This change in resistance can be used to control the flow of current in a circuit, allowing for the detection of light levels and the control of light-activated devices.
