1. Wireless Sensor Network Overview
The LORD Sensing Wireless Sensor Network is a high- speed, scalable, sensor data acquisition and
sensor networking system. Each system consists of wireless sensor interface nodes, a data collection
gateway, and full- featured user software platforms based on the LORD Sensing Lossless Extended
Range Synchronized (LXRS) data communications protocol. Bi- directional wireless communication
between the node and gateway enables sensor data collection and configuration. Gateways can be
connected locally to a host computer or remotely via local and mobile networks. Some gateways also
feature analog outputs for porting sensor data directly to stand-alone data acquisition equipment.
The selection of available nodes allows interface with many types of sensors, including accelerometers,
strain gauges, pressure transducers, load cells, torque and vibration sensors, magnetometers, 4 to 20mA
sensors, thermocouples, RTD sensors, soil moisture and humidity sensors, inclinometers, and orientation
and displacement sensors. Some nodes come with integrated sensing devices such as accelerometers.
System sampling capabilities include lossless synchronized sampling, continuous and periodic burst
sampling, and data logging. A single gateway can coordinate many nodes of any type, and multiple
gateways can be managed from one computer with the SensorConnect and SensorCloud software
platforms. Integration to customer systems can be accomplished using OEM versions of the sensor nodes
and leveraging the LORD Sensing data communications protocol.
Common wireless applications of LORD Sensing Sensing Systems are strain sensor measurement,
accelerometer platforms, vibration monitoring, energy monitoring, environmental monitoring, and
temperature monitoring.

2. Node Overview
The G- Link- 200 wireless accelerometer node features an on- board triaxial accelerometer that allows
high- resolution data acquisition at noise levels as low as 25 or 80 µg√Hz. The G- Link- 200 can output
continuous waveform data, or one of four derived channels, including Velocity (IPSrms), Amplitude (Grms
and G pk- pk ) and Crest Factor, allowing long- term monitoring of key performance indicators while
maximizing battery life.
G-Link-200 inputs are 20-bit resolution with ± 0.1% full scale measurement accuracy. The node can log
data to internal memory, transmit real-time synchronized data, and it supports event driven triggers with
both pre- and post- event buffers.
To acquire sensor data, the G-Link-200 is used with a LORD Sensing data gateway such as the WSDA-
200 USB or WSDA-2000.

2.3 Node Operational Modes
Sensor nodes have three operational modes: active , sleep , and idle . When the node is sampling, it is in
active mode. When sampling stops, the node is switched into idle mode, which is used for configuring
node settings, and allows toggling between sampling and sleeping modes. The node will automatically
go into the ultra low-power sleep mode after a user-determined period of inactivity. The node will not
go into sleep mode while sampling.
