Understanding LDR Sensors – Photo-Resistors and Their Practical Implementations 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 https://futureblogspot42.blogs-service.com/69883170/the-most-spoken-article-on-ldr-sensor
