Comprehending Photoresistor 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://proscope86.blazingblog.com/38922561/the-qualities-of-an-ideal-ldr-resistor-circuit
