Exploring Photoresistor Sensors – Photo-Resistors and Their Practical Implementations A Light Sensor Resistor or sensor LDR 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://vividcompass32.blogoxo.com/39244930/yes-good-ldr-sensor-do-exist
