System Connections

To acquire sensor data the following components are needed: user- supplied external , a LORD

Sensing wireless sensor node, a LORD Sensing data gateway, and a host computer with access to the

data acquisition software.

The sensor, node, gateway, and software selection are application-dependent, but the basic interfaces

are the same.
