Laser receiver Sensor Module
The Laser Receiver Sensor Module is a compact detection module designed to sense the presence of a laser beam and provide a digital output signal. Operating at 5V DC, the module outputs a HIGH level when a laser signal is detected and a LOW level when no laser signal is present. It uses a non-modulated laser receiver, making it suitable for indoor applications where ambient light interference is minimal. Due to its sensitivity to external light sources such as sunlight and bright lamps, the module performs best in dark or controlled lighting environments for reliable laser detection.
وحدة مستشعر استقبال الليزر هي وحدة استشعار مدمجة مصممة للكشف عن وجود شعاع ليزر وإعطاء إشارة خرج رقمية. تعمل بجهد 5 فولت DC وتنتج إشارة مرتفعة (HIGH) عند استقبال شعاع الليزر وإشارة منخفضة (LOW) عند عدم استقباله. تعتمد الوحدة على مستقبل ليزر غير معدل (Non-Modulated) مما يجعلها مناسبة للاستخدامات الداخلية ذات الإضاءة المتحكم بها. ونظرًا لحساسيتها لمصادر الضوء الخارجية مثل أشعة الشمس والإضاءة القوية، فإن أفضل أداء لها يكون في البيئات المظلمة أو ذات الإضاءة المحدودة لضمان دقة الكشف.
The Laser Receiver Sensor Module is an electronic sensing device used to detect laser light and convert it into a digital output signal that can be read by microcontrollers, development boards, and automation systems. The module is designed for applications such as laser security systems, object detection, positioning systems, and educational electronics projects.
When the receiver detects a laser beam, the output switches to a HIGH logic level, indicating the presence of the laser signal. When the laser beam is interrupted or absent, the output changes to a LOW logic level. This simple digital interface allows easy integration with platforms such as Arduino, Raspberry Pi, ESP32, and other embedded systems.
The sensor uses a non-modulated laser receiver, meaning it directly detects continuous laser light without filtering specific modulation frequencies. As a result, strong ambient light sources such as sunlight, fluorescent lamps, or intense indoor lighting may affect detection accuracy. For optimal performance, the module should be used indoors in dark or controlled-light environments.
Its compact PCB size makes it suitable for installations where space is limited while maintaining reliable laser detection capabilities.
