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 unique sensor varies its resistance based on the level of light falling on it. When exposed to bright light, its resistance decreases, and when https://keenhub26.digitollblog.com/38807013/what-might-be-next-in-the-ldr-resistor-circuit
