Product Overview
The LDR (Light-Dependent Resistor) module features a 5mm photoresistor that adjusts resistance based on ambient light intensity, making it perfect for light-sensitive applications. Constructed with cadmium sulfide (CdS), this sensor delivers high sensitivity and rapid response to varying light conditions, ensuring accurate detection in both bright and low-light environments. The module is designed for seamless integration into circuits, providing a cost-effective solution for projects requiring light-dependent automation. Its compact form factor and standard electronics-grade build ensure durability and consistent performance. Whether used for prototyping or embedded systems, this LDR module offers reliable light-sensing capabilities without requiring complex calibration. The onboard design simplifies wiring, allowing for quick deployment in educational experiments, hobbyist projects, or small-scale industrial applications.
FAQs
1. How does the LDR module respond to different light levels?
The resistance decreases as light intensity increases, allowing the sensor to trigger connected circuits based on ambient brightness.
2. Can this LDR be used with Arduino or Raspberry Pi?
Yes, the module is compatible with microcontrollers like Arduino and Raspberry Pi for light-sensing projects.
3. What is the typical resistance range of this LDR?
Under darkness, resistance can exceed 1MΩ, while in bright light, it drops to around 100Ω–1kΩ.
4. Is this LDR suitable for outdoor applications?
While functional outdoors, prolonged exposure to moisture or extreme temperatures may affect performance. Use protective enclosures if needed.
5. How should I store the LDR module when not in use?
Keep it in a dry, dust-free environment away from direct sunlight to maintain sensitivity and longevity.
