🔆 12mm 12528 LDR – 10-20K (2Pcs) 🔆
The 12528 LDR (Light Dependent Resistor) is a photoresistor whose resistance changes according to light intensity. Its resistance decreases in bright light (10–20KΩ at 10Lux) and increases in darkness, making it suitable for automatic lighting systems, light-following robots, and day/night detection circuits. This pack includes 2 pieces for multiple DIY applications.
