Exploring LDR Sensors – Photo-Resistors and Their Uses A Light Sensor Resistor or sensor LDR 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://vividblock118.bleepblogs.com/39262273/essential-things-you-must-know-on-sensor-idr
