LDR sensor 12mm – Light Dependent Resistor Photoresistor
It looks like you re referring to 12MM LDR, but could you clarify what LDR stands for in your context? LDR can stand for several things depending on the field (e.g., Light Dependent Resistor, Low Density Residential, etc.), and 12MM could refer to a measurement like 12 millimeters. The 12mm LDR (Light Dependent Resistor) is a photoresistor that changes resistance based on light intensity, making it ideal for light sensors, automatic street lights, and Arduino smart systems. Large surface area for improved sensitivity.
