Understanding Light Dependent Resistors (LDRs) – Light Dependent Resistors and Their Uses A Photoresistor or photoresistive sensor is an crucial component widely used in light-sensing electronic circuits. This special sensor varies its resistance based on the amount of light falling on it. When subjected to bright light, its resistance drops, https://revolutionaryzone09.blogsvila.com/39204629/the-qualities-of-an-ideal-ldr-sensor
