Product Description

The Industrial 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 precision sensors used in Building Science research.

 

The Industrial WiDAQ has the ability to communicate both wireless and wired to the SMT Building Intelligence gateway. When wired, the Industrial WiDAQ can serve as a CAN coordinator for other wireless WiDAQs. This configuration offers several benefits over a wireless only system as wired nodes act as coordinators for remote nodes resulting in increased battery life and facilitates wireless deployment in areas where wireless communication is not sustainable. The wired backbone operates over the industry standard Controller Area Network (CAN) permitting dense sensor deployments in harsh environments.

Application

+

Building Science Research (long term)

  • Window and wall module evaluation. 
  • External façade sensing

 

Green Roof Research

  • Mass moisture and temperature sensing

 

Field Applications/ResearchLong term structure monitoring

  • Targeted repair monitoring
  • See the Mobile WiDAQ datasheet for fast deployment, short term monitoring solutions.

Features

+

  • Eight resistance channels capable of reading wide moisture content ranges and precision thermistors.
  • Circuitry is housed in a NEMA IP66 rated enclosure suitable for outdoor installations.
  • Sensor inputs use screw down terminal connectors for universal field configurations. No special crimp tools required.
  • Resistance measurements can be performed in either positive or negative polarity for the purpose of negating half cell voltages or diode effects in monitored structures.
  • Each input is optically isolated from each other and earth ground preventing ground loops and external noise influences on the measurement (wireless mode operation).
  • Integrated Temperature Sensor
  • Communicates to SMT Building Intelligence Gateway (BiG) via USB WiKey or wired CAN clusterhead device.
  • Powered by 4 AA batteries for long term monitoring.
  • Optional built in solar panel for long term monitoring when used outdoors.
  • Can be configured via on-board dip switches to measure up to eight micro-voltage channels.
