Understanding LDR Sensors – Photo-Resistors And Their Practical Implementations 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 illuminated by bright light, its resistance reduces, and https://proworld342.izrablog.com/39304377/yes-good-ldr-resistor-circuit-do-exist
