Understanding LDR Sensors – Photo-Resistors And Their Practical Implementations A Light Sensor Resistor or sensor LDR is an essential component commonly utilised 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://sharpnode20.blog4youth.com/39468553/yes-good-ldr-sensor-do-exist
