Understanding LDR Sensors – Light Dependent 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, https://creativelevel220.mybloglicious.com/58817598/latest-news-on-ldr-resistor-circuit
