4GHz Wireless Networked DAQ Module Description

2.4GHz Wireless Networked DAQ Module

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
