Exploring Photoresistor 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://meganode10.theideasblog.com/39423225/the-benefits-of-knowing-ldr-resistor-circuit
