The Background Of Smart Dust, By Kris Prister
stands for micro electromechanical sensors which is a tiny particle with extraordinary capabilities starting from sensing its environment , computing with the help of wireless communication capabilities.

Smart dust was first discovered by Kris Prister at the
University of California, Berkley.
Smart Dust is a self-contained network of tiny motes(a speck) each mote has the capability of sensing and monitoring the environment conditions and update them.They are also known as SMART MATTER.
They are tiny particles which act as sensors and will be around the size of a grain of sand.At present the achievable size of the grain is around 5mm cube.
They contain sensors which have the computable capability, …show more content…
Once the readings were taken, the mote transformed them into digitized data, sent them to the radio and waited until all data was sent before switching to the sleep mode. In detail, the processor received sensor readings from the embedded 10-bit Analog-to-Digital Converter (ADC). If the data was taken correctly, the onboard light emitting diodes (or LEDs) lit up to signal the proper functioning of the mote. Analog to digital conversion was performed on the readings, after which the data was integrated into the packet to be transmitted.
The default packet format was slightly modified to fit the size and format of the data to be transmitted. In other words, the on-board temperature was replaced by the “alien” moisture reading. The packet was then sent to the radio and transmitted over the network until it reached the base station. The base station was connected to a laptop through a serial port. The data is then collected using a LabVIEW graphical user interface (GUI) developed here,the data from the serial port is collected deciphered and shown as the output or displayed by the GUI. If an error is detected, it was display the error and sometimes in few cases it saves the contents in other cases the resulsta are ignored or deleted
