Understanding LDR Sensors – Photo-Resistors and Their Practical Implementations 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 https://keenhub26.digitollblog.com/38807013/what-might-be-next-in-the-ldr-resistor-circuit
