Description: A photonic sensor is a device that uses photons, the elementary particles of light, to detect and measure light across various wavelengths. These sensors are fundamental in modern technology as they enable the conversion of optical signals into electrical signals, facilitating the capture of information about the environment. Photonic sensors are highly sensitive and can detect subtle changes in light intensity, making them ideal for applications in various fields such as medicine, security, and industrial automation. Additionally, their ability to operate in extreme conditions and their compact size make them an attractive option for integration into IoT (Internet of Things) devices. In the context of IoT, photonic sensors can be used to monitor environmental conditions, such as air quality or temperature, and send real-time data to analysis systems, enhancing decision-making and operational efficiency. Their relevance in today’s technology lies in their ability to provide accurate, real-time data, which is essential for the development of smart, connected solutions.
