Understanding Photoresistor 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://pragmaticdistrict54.59bloggers.com/39308881/the-growing-craze-about-the-ldr-sensor
