Smart Dust refers to tiny, wireless sensors that can detect and collect data about their environment. These miniature devices, often the size of a grain of sand, can monitor various factors such as temperature, light, and motion. They communicate with each other and transmit information to a central system for analysis. The potential applications of Smart Dust are vast, ranging from environmental monitoring to healthcare. For instance, they could be used in agriculture to track soil conditions or in smart cities to optimize traffic flow. Their small size and low power requirements make them suitable for a wide range of uses.
