Understanding LDR Sensors – Light Dependent Resistors and Their Uses A Light Sensor Resistor or photoresistive sensor is an essential component widely used in photo-sensitive electronic circuits. This special sensor varies its resistance based on the amount of light falling on it. When subjected to bright light, its resistance decreases, https://wisenode32.alltdesign.com/the-most-spoken-article-on-ldr-resistor-circuit-57627014
