A digital sensor is a device that converts physical phenomena, such as light, temperature, or pressure, into digital signals that can be processed by computers or other electronic systems. These sensors are widely used in various applications, including smartphones, cameras, and industrial equipment, to gather data and enable automation. Digital sensors often utilize technologies like semiconductors and microcontrollers to enhance their accuracy and efficiency. They play a crucial role in the Internet of Things (IoT), allowing devices to communicate and share information seamlessly, which leads to smarter and more responsive systems in everyday life.
