Light Sensitive Photo Resistor
$0.54The 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.

Photoresistor Light Sensor Module for Arduino
$3.24A photoresistor light sensor module for Arduino is a component that allows for the measurement of ambient light levels using a photoresistor. Photoresistors, also known as light-dependent resistors (LDRs), are electronic components that change resistance based on the amount of light that they receive.
A photoresistor light sensor module for Arduino is designed to be used with the popular open-source electronics platform and typically contains a photoresistor and a few other electronic components that allow it to interface with the Arduino board. The module is connected to the Arduino board through its analog input pins, which allow it to measure the analog voltage produced by the photoresistor.
