LDR 5MM Photoresistor 5528 Light Dependent Resistor
The LDR 5528 5mm Photoresistor is a light-dependent resistor designed for detecting ambient light levels in electronic circuits. Its resistance decreases as light intensity increases, making it ideal for automatic lighting systems, brightness control, and sensor-based projects. With a compact 5mm size, simple operation, and low cost, it is widely used in Arduino, ESP, robotics, and educational electronics applications requiring reliable and easy-to-integrate light sensing functionality.
يعد LDR 5528 Photoresistor بحجم 5mm مقاومة ضوئية حساسة للضوء تستخدم لقياس شدة الإضاءة في الدوائر الإلكترونية. تنخفض مقاومتها كلما زادت الإضاءة الساقطة عليها، مما يجعلها مناسبة لأنظمة الإضاءة التلقائية والتحكم بالسطوع والمشاريع المعتمدة على الحساسات. يتميز بحجمه الصغير وسهولة استخدامه وتكلفته المنخفضة، ويستخدم بشكل واسع في مشاريع Arduino وESP والروبوتات والتجارب التعليمية الإلكترونية.
The LDR 5528 5mm Photoresistor is a light-sensitive resistor designed to detect and respond to changes in ambient light intensity. It belongs to the family of Light Dependent Resistors (LDRs), where the electrical resistance changes according to the amount of light falling on the sensor surface.
In dark conditions, the resistance becomes very high, while exposure to brighter light significantly lowers the resistance. This behavior allows the component to be used in automatic sensing and light-controlled electronic systems.
The compact 5mm sensor head makes it suitable for small electronic circuits and embedded projects. The sensor can easily interface with microcontrollers such as Arduino, ESP32, Raspberry Pi, and other development platforms using simple voltage divider circuits.
The LDR 5528 is commonly used in automatic lighting systems, smart street lamps, display brightness adjustment, robotics, and educational electronics projects due to its simplicity, reliability, and low cost.
