Light Dependent Resistor
SKU:AX22-0005
Low stock: 5 left
This AX22-sized module houses a light-dependent resistor with a dark resistance of 100 kΩ – 200 kΩ on a 22 × 22 mm PCB, yielding an analog voltage that smoothly follows ambient brightness and is effortless for any microcontroller’s ADC to read. It slots straight into AX22 systems with no special wiring, enabling automatic daylight detection, adaptive backlight dimming, or simple light-triggered events in minutes. Ideal for smart lamps, environmental loggers, or interactive installations where responsive, light-aware behavior is essential.
