Understanding LDR Sensors – Photo-Resistors And Their Practical Implementations A Light Dependent Resistor (LDR) or sensor LDR is an essential component commonly utilised in photo-sensitive electronic circuits. This special sensor alters its resistance based on the level of light falling on it. When illuminated by bright light, its resistance reduces, https://smarthub453.collectblogs.com/83494224/ldr-resistor-circuit-knowing-the-best-for-you
