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 special sensor varies its resistance based on the amount of light falling on it. When subjected to bright light, its resistance reduces, and when https://sharpdock229.idblogz.com/39286062/the-growing-craze-about-the-ldr-sensor
