Understanding Light Dependent Resistors (LDRs) – Light Sensors And Their Applications A Photoresistor or LDR sensor is an important component widely used in illumination detection electronic circuits. This unique sensor changes its resistance based on the amount of light falling on it. When subjected to bright light, its resistance drops, https://brilliantventure652.blogdon.net/the-blog-on-ldr-resistor-circuit-54908325
