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 illuminated by bright light, its resistance reduces, and when https://bestcontent99.blogsvila.com/39204271/yes-good-ldr-resistor-circuit-do-exist
