Digital sensors are devices that convert physical phenomena, such as light, temperature, or pressure, into digital signals that can be processed by computers or other electronic systems. They play a crucial role in various applications, including smartphones, cameras, and industrial equipment, enabling accurate data collection and analysis. These sensors work by detecting changes in their environment and translating those changes into numerical values. For example, a temperature sensor measures heat levels and sends the data to a microcontroller for further processing. This technology is essential for automation, monitoring, and improving efficiency in many fields.
