Understanding Photoresistor Sensors – Light Dependent 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 subjected to bright light, its resistance drops, https://brightcenter19.bloggactivo.com/37986201/the-qualities-of-an-ideal-ldr-sensor
