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 reduces, and https://adaptivestream885.blognody.com/45305224/why-you-need-to-know-about-sensor-idr
