ioBridge is a manufacturer of Internet-based monitor and control hardware and a provider of seamlessly integrated cloud-based social Web 2.0 folksonomies and curated online API webservices, using WebSocket, JSON and a host of other related technologies.

Jason Winters and Hans Scharler founded ioBridge in Gainesville, Florida on July 26, 2008.

In December 2008, ioBridge released the IO-204 Monitor and Control Module and web services platform to connect electronics projects online such as an iPhone-controlled dog treat dispenser[1] and a toaster that could post to Twitter.[2]

In 2009, ReadWriteWeb chose the IO-204 Module as one of its "Top 10 Internet of Things Products of 2009",[3] and Ben Arnold from the Consumer Electronics Association (CEA) explored the possibilities of using the IO-204 for social-network-aware home automation in the article "Growing the connected home ecosystem".[4]

User projects using the ioBridge module and web services have been featured on popular technology blogs such as Engadget[5][6][7] and Hackaday.[8][9]

IO-204 Module[edit]

The IO-204 Module connects to a Local Area Network using 10/100/1000Base-T Ethernet and then establishes an encrypted connection to ioBridge web servers.

The IO-204 has four GPIO channels. Each channel includes a 5 V power line, a ground connection, digital input pin, analog input pin, and a digital output pin. The digital input line is capable of reading voltages of 0 V and 5 V and pulse counting. The analog input is 10-bit resolution for voltages varying between 0 V and 5 V. The digital output line outputs 0 V and 5 V at 20 mA and is capable of sending pulses and serial data.

Each channel supports smart boards[10] to add serial communication for microcontrollers such as Arduino or BASIC Stamp, servo control, or X10 outlet and light control.

The module provides 1 KB of on-board logic storage for rules defined by the user. A rule is a set of conditions and actions based on time, input conditions, output conditions, and online/offline status.

The IO-204 requires a regulated 5 V power adapter with a minimum of 1 A and a maximum of 4 A.

Web services[edit]

ioBridge modules are accessed via an hosted web interface for configuration, control, and monitoring from a web browser supporting Ajax, JavaScript, CSS, and HTML. Features of the web service include a drag-and-drop dashboard, data logging, data charting, widget creation, and email alerting.

APIs allow the web services to be extended and integrated into third-party applications[11] using a RESTful interface.
