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 level of light falling on it. When illuminated by bright light, its resistance reduces, and https://visionarygateway54.digitollblog.com/38806579/how-much-do-you-know-about-ldr-sensor
