Understanding LDR 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 subjected to bright light, its resistance drops, and https://ultrawave08.thezenweb.com/the-most-spoken-article-on-sensor-idr-77269462
