Understanding Light Dependent Resistors (LDRs) – Photo-Resistors and Their Uses A Photoresistor or LDR sensor is an essential component commonly utilised in photo-sensitive electronic circuits. This special sensor changes its resistance based on the intensity of light falling on it. When illuminated by bright light, its resistance reduces, and when https://infinitearc21.blogsidea.com/45573142/yes-good-sensor-idr-do-exist
