<ul data-eligibleForWebStory="false"><li>LDR sensor, or Light Dependent Resistor, changes its electrical resistance based on light intensity, with resistance dropping in light and increasing in darkness.</li><li>The working principle of an LDR sensor is based on photoconductivity, where light photons hitting the material make it more conductive, leading to a decrease in resistance.</li><li>LDR sensors respond to different light intensities by varying resistance, with resistance reaching megaohms in darkness and dropping to a few hundred ohms in bright light.</li><li>Advantages of LDR sensors include cost-effectiveness, ease of use, and versatility in light detection and brightness control, while disadvantages include slower response compared to other sensors and temperature sensitivity.</li></ul>
