The
Mobile Wireless Data Acquisition Node (WiDAQ) is a high precision measurement
device designed for distributed remote sensor data acquisition. The built-in 24-bit A/D converter and low
noise high precision measurement circuitry facilitates data acquisition from a
wide variety of sensors.
The
Mobile WiDAQ communicates directly to the SMT Building Intelligence gateway or via
a CAN coordinator when used in a hybrid wireless/wired configuration. This configuration offers several benefits
over a wireless only system as wired nodes act as coordinators for wireless
nodes allowing Mobile WiDAQs to conserve battery power.
Applications
Building Science Research (short term)
Restoration Monitoring
Short term structure monitoring
Targeted repair monitoring
See the Industrial WiDAQ datasheet for long term
monitoring and custom applications.
Features
Four
resistance channels capable of reading wide moisture content ranges and
precision thermistors.
Sensor
inputs use compact audio jacks for easy connectivity.
Resistance
measurements can be performed in either positive or negative polarity for the
purpose of negating half cell voltages in the monitored structure
Each
input is optically isolated from each other and earth ground preventing ground
loops and external noise influences on the measurement.
Built
in Humeril HTM1735 Relative Humidity Sensor
· Integrated
Temperature Sensor
Auxiliary
input for high precision microvolt measurement capable of reading
thermocouples, heat flux sensors, displacement sensors and external relative
humidity sensors.
Communicates
to SMT Building Intelligence Gateway (BiG) via USB WiKey or wired CAN
clusterhead device.
