Overview
SNS2100
is a 2.4GHz wireless networked DAQ module for vast array of distributed
monitoring and control applications. SNS2100 modules are deployed at several
distributed points and inter-connected by a dynamically configurable wireless
network that enables the transfer of acquired data from each module to the PC,
via a base station module using USB. SNS2100 has an internal Li-Ion
rechargeable battery that can run 100 hours or more operating continuously, and
up to 5,000 hours operating only when needed using Sleep/Wakeup function. It
can also operate from an external power source.
Multi Channel / Multi-Hop
SNS2100
module is based on Carrier Sense Multiple Access(CSMA) for multi channel
communication and the communication architecture supports both direct and
multi-hop message packet delivery. Multi-hop communication enables the communication
range to be extended even further. For instance, the range can be increased
three-fold using three nodes configured as a three-hop network. SNS2100 is
especially useful in fields where cable installation is costly or tedious.
Automatic Network
Configuration
SNS2100 modules
are dynamically network configurable which greatly eases the installation
procedure. There is no need to go through strenuous network configuration
procedures as one would encounter setting up the I.P. address for connection to
the internet. The protocol and messaging strategy supports random topologies.
Reliable
Data Transmission
SNS2100 offers both data
detection and Forward Error Correction (FEC) algorithm for reliable data
transmission. SNS2100 also has an internal non-volatile memory of 256kbytes so
that the readings can be stored locally and later be transferred to the base
station. Since it can store all it’s readings, it is easier to make reliable
retransmissions of data to the base station in case of communication error.
Built-In
Analog Signal Processing
SNS2100 is
designed mainly for measuring bridge-based sensors such as strain sensors, of
both 120ohm and 350ohm impedance. It has an internal Wheatstone bridge and a
x1000 differential amplifier so that the output of the strain sensor can be
directly connected to the unit for measurement, without any additional
hardware.
Support
for OEM Products
softDSP’s expertise in analog
signal processing allows easy migration from the current input analog circuitry
design to the one required by our OEM customer. A wide range of input range,
filtering, can be provided from up to 6 input channels per node Click
