"220V Cooling Fan" Things actually called sensor network in a foreign country, it is a sensor-based build a new network, and there are three elements, one sensor, is what we usually refer to the perception part, too Things are tactile system, away from the sensor networking lost data sources, leaving the sensor, "220V Cooling Fan" became passive water without trees. Second, the network, no network, huge amounts of data generated by the sensor can not transfer data blocked fracture, its value will be greatly reduced. Third, cloud computing, with the network will naturally form clouds, leaving the cloud, the data "220V Cooling Fan" will be generated by the sensor data rubbish piled garbage mountain farm, meaningless, massive data mining is effective sensor networks value.
