Overview
1.1 The FlatMesh System
A FlatMesh network consists of a number of nodes connecting to one
gateway device. In some situations multiple networks may be required
on a single site, for example a site in which the number of nodes ex-
ceeds the number supported by a single Gateway, or a site where there
are a set of separate measurement zones.
A FlatMesh Node is a sensing unit with an integrated wireless mesh
radio and battery. It participates in a FlatMesh wireless network, for-
warding messages as required by the system, and also takes samples
from onboard and/or external sensors. Sampling is done on a periodic
schedule which may be either fixed or variable. In addition, a sample
may be manually requested via the Gateway.
1.2 FlatMesh Nano / NanoPlus / NanoMacro
Nodes
The FlatMesh Nano family contains a high precision triaxial tilt sen-
sor. This sensor measures the orientation of the node relative to the
direction of gravity using a MEMS accelerometer.
