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 illuminated by bright light, its resistance reduces, and https://integralframework763.tinyblogging.com/the-blog-on-ldr-sensor-82868719
