WiFi tags put sensing in the clouds

摘要

A credit card sized PCB uses standard IEEE 802.11 b/g WiFi connections to transfer sensor data to client servers and web browser pages through the cloud of computing power that constitutes the Internet. Developed by Cores Electronics in Austin, Texas, the makers of the Tag4m, as it is designated, are presently targeting it at the oil, gas and water industries, but its ￡100 price starting price makes itrnsuitable for any industrial application involving distributed sensing, especially as its configuration allows it to be used to additionally undertake simplerncontrol tasks.
