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 exceeds 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 net-
work, forwarding 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 Optical Displacement Node (ODS)
The FlatMesh Optical Displacement Node provides the ability to
measure distance between the node and a target. It also provides
temperature and onboard battery voltage. The unit can optionally
be configured with an internal tilt meter.
Note
Readings can be scheduled anywhere between 15 seconds to
twelve hours with a time increment of one second.
