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.

Building Science Research (short term)

Restoration Monitoring

Short term structure monitoring

Targeted repair monitoring
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.

Easy accessible standard 9V battery.
