What is Smart Dust?
Smart dust refers to tiny, wireless micro-electromechanical systems (MEMS) with the capability to sense, process, and communicate environmental data. These minuscule devices are packed with sensors, processors, and communication components, enabling advanced data collection and transmission on an unprecedented scale.
How Smart Dust Works
Each smart dust particle acts as a node in a distributed network. These particles collect data from their surroundings and wirelessly transmit it to a central hub for analysis. Key components include:
- Sensors: To measure temperature, humidity, pressure, light, and more.
- Processors: For data computation and decision-making.
- Power Source: Often solar or energy harvesting methods.
- Communication Module: For wireless data transfer using protocols like Bluetooth or Zigbee.
