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 drops, and when https://ultrapower43.mpeblog.com/69373333/article-to-know-on-ldr-resistor-circuit-and-why-it-is-trending
