Understanding LDR Sensors – Photo-Resistors and Their Uses A Light Sensor Resistor or photoresistive sensor is an essential 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, and when https://virtualwave785.prublogger.com/37839650/readers-views-point-on-ldr-resistor-circuit-and-why-it-is-trending-on-social-media
