Restraints

• Competition from Infrared and Camera-Based Technologies in the Light Sensor Market

The light sensor market faces growing competition from alternative technologies, particularly infrared sensors and camera-based systems, which can sometimes offer better performance, additional features, or cost-effectiveness in certain applications, limiting the adoption of light sensors. Infrared sensors are commonly used in proximity detection, motion sensing, and temperature measurements. These sensors excel in environments with fluctuating or low-light conditions, as they can detect heat signatures and motion without being impacted by ambient light. This ability makes infrared sensors more reliable in applications where light sensors may struggle, such as in dark settings or precise detection tasks. Their integration into consumer electronics, automotive systems, and security devices is becoming increasingly popular due to their versatility and ability to function in diverse environments. On the other hand, camera-based systems, which rely on computer vision and machine learning, provide more advanced functionalities that light sensors cannot offer. These systems are often used for tasks like object detection, facial recognition, and advanced imaging, which go beyond simple light measurement. While camera-based systems typically demand more processing power and are costlier, they deliver superior performance for complex tasks such as those required in automotive safety features or high-quality smartphone photography.
