WebDAQ
Digilent WebDAQs are a line of stand-alone data loggers designed for remote monitoring, analysis, and control. There are three devices in the WebDAQ Series. Devices are available to log multiple signal types including voltage (up to +/-60 V), thermocouples, IEPE-based sensors like accelerometers, current, RTDs, resistance, and bridge-based sensors. All the intelligence is built into the WebDAQ, eliminating the need for a PC or additional software. By using the embedded WebDAQ web server, users can easily configure simple or sophisticated applications, log data, update digital outputs and/or send notifications based on alarm conditions. Real-time data can be viewed from any location and any device with a web browser, including standard personal computers and smartphones. WebDAQs can log remotely or locally, with sufficient local storage for long-term monitoring applications, as well as the ability to log data only when certain signal conditions are detected - and send various kinds of alerts and notifications when important events occur.
