Wireless Precision Data Acquisition Node - Overview

General Description

WiDAQ Product Picture The Wireless Precision Data Acquisition Node (WiDAQ) is a high precision measurement device designed for remote structure monitoring. 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 hybrid wireless/wired capability of the WiDAQ offers several benefits over a wireless only system. Wired nodes act as coordinators for the wireless nodes which allow wireless units to conserve battery power. The wired backbone operates over a robust Controller Area Network (CAN) and permits dense sensor deployments in harsh environments.
