A typical "smart dust" particle, often called a "mote", is primarily composed of a sensor to detect environmental data, a processing unit (microcontroller) to interpret the sensor data, a communication transceiver to send information wirelessly, and a power source like a small battery or energy harvesting mechanism, all integrated into a tiny package with minimal size and power consumption; essentially, a sensor, a processing circuit, a communication module, and a power supply.
