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 amount of light falling on it. When illuminated by bright light, its resistance reduces, and https://vividview541.blogoscience.com/45480266/the-most-spoken-article-on-ldr-sensor
