EasyDAQ + ioBridge = Web Controlled Relays

EasyDAQ is the creator of a wide range of relay controllers with USB, Ethernet, Serial, and XBee interfaces. EasyDAQ partnered with ioBridge to web-enable their serial relay control modules. The integrated system includes web-based control of up to 16 opto-isolated relays, a custom serial cable that interfaces the serial relay controller to the ioBridge IO-204 module, and an international / universal power supply.

EasyDAQ and ioBridge Serial Relay Controller System Overview

Web access is provided by the ioBridge.com platform via widgets and the Static Widget API. The API provides a conduit for commands sent by HTTP or HTTPS POST/GET requests. HTML, LabVIEW, Java, Perl, Python, Ruby, PHP and Ajax are access/programming options. Refer to the ioBridge Wiki for protocol and information on controlling the EasyDAQ SER8PRMx and SER16PRMxN relay cards using the ioBridge.com platform.

The system components are available for sale and worldwide distribution directly from EasyDAQ – visit EasyDAQ.biz for more information.

Wireless Robot with Web Controls

Any good SkyNet starts with a robot. Well, we are in luck…User “badcat89″ posted in our forum about a Web-enabled, Wireless Robot that is controlled via a web interface. We can imagine a swarm of robots controlled by data received from the web.

The robot uses a pair of serial bluetooth adapters to form a wireless link with the ioBridge IO-204. The serial levels of the IO-204 are TTL and a circuit using the MAX-232 was required to allow the serial interface work properly. On the robot is a set of serial servo drivers that control the steering and speed.

The interface is standard web page using an embedded ioBridge.com serial widget to make the connection to the IO-204 base station module. You can control the direction and throttle by clicking on the itnerface and using the up and down arrow keys on your keyboard. The interface generates serial strings that the serial servo drivers react to when received. You can see the strings and the serial widget in the debug part of the web interface.

Here is a YouTube video of the web powered robot in action – looks like a lot of fun to drive. One step closer…

ioBridge Global Network

We put together this Google map showing the span of the ioBridge network. When we first went public with our beta hardware back in November, we were caught off guard by the demand from international customers.  Honestly, we didn’t even know how well our hardware and web applications would work spanning such large distances.  A few brave beta testers in the Netherlands and Australia decided to take a change and try out our hardware anyway.  We soon found out that the ioBridge system latency was still very good and gave these users near real-time control capabilities over the Internet.  We think this is amazing considering that some of these command messages are literally circling the globe!

An interesting point to make about all the points you see on the map is that any of them can be linked. By using our Serial Smart Boards, a serial based sensor attached to a module in Singapore can send readings to an LED scrolling sign in London.

We’re hard at work on more linking features.  Soon ioBridge users will be able to connect digital inputs and outputs from modules anywhere in the world.  The transcontinental ioBridge light-switch isn’t far off!
