Understanding LDR Sensors – Photo-Resistors and Their Uses A Light Sensor Resistor or photoresistive sensor is an essential component widely used in light-sensing electronic circuits. This special sensor varies its resistance based on the amount of light falling on it. When subjected to bright light, its resistance drops, and when https://novachain652.digitollblog.com/38807239/why-you-need-to-know-about-ldr-sensor
