IoBridge

IoBridge is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand IoBridge rather than just read about it. In short: 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 June 26, 2008.

Key takeaways

IoBridge belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect IoBridge to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of IoBridge from memory before moving on to harder problems.

Reference excerpt

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 June 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 and a toaster that could post to Twitter. In 2009, ReadWriteWeb chose the IO-204 Module as one of its "Top 10 Internet of Things Products of 2009", 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". User projects using the ioBridge module and web services have been featured on popular technology blogs such as Engadget and Hackaday.

IO-204 Module 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 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 ioBridge modules are accessed via an ioBridge.com 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 using a RESTful interface.

Worked examples

Example 1 — a first encounter with IoBridge

Start with the simplest possible case. Write down what IoBridge claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to IoBridge before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about IoBridge ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of IoBridge

In research: IoBridge appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses IoBridge in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: IoBridge is common in secondary-school and first-year university syllabi. It links to neighbouring topics Internet of things, so understanding it makes those chapters shorter.
In everyday life: Look for IoBridge outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is IoBridge in simple terms?

Why does IoBridge matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study IoBridge?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
