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://resilientstation108.blogzag.com/82252931/essential-things-you-must-know-on-ldr-resistor-circuit
