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 automated manufacturing, 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 and sends the information as a digital signal, allowing systems to respond accordingly. This technology enhances efficiency and precision in numerous fields, from healthcare to automotive engineering.
