Understanding LDR Sensors – Photo-Resistors and Their Uses A Light Sensor Resistor or photoresistive sensor is an essential component widely used in photo-sensitive electronic circuits. This special sensor varies its resistance based on the amount of light falling on it. When subjected to bright light, its resistance reduces, and when https://unifiedcircle86.look4blog.com/76705776/how-much-do-you-know-about-ldr-sensor
