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 unique sensor varies its resistance based on the amount of light falling on it. When subjected to bright light, its resistance drops, https://alphaportal819.tblogz.com/how-much-do-you-know-about-sensor-idr-52066460
