A Low-Cost Connection to the IoT

In Circuit Cellar’s March issue, columnist Jeff Bachiochi tests the services of a company he says is “poised to make a big impact” on the Internet of Things (IoT).

This shows the I2C interface Bachiochi designed to enable available clamp-on current sensors to be monitored. He added four of these circuits to a PCB, which includes the circuitry for an imp card.

This shows the I2C interface Bachiochi designed to enable available clamp-on current sensors to be monitored. He added four of these circuits to a PCB, which includes the circuitry for an imp card.

Established in 2011, Electric Imp offers a flexible connectivity platform meant to enable any device to be connected to the IoT. The platform, called the “imp,” provides an SD-card sized module (including an 802.11b/g/n Wi-Fi radio package) that can be installed on any electronic device to go online. A powerful processor runs the imp OS.

“You only need to supply an SD card socket (and a few other components) to your product to give it connectivity,” Bachiochi says. “The imp’s processor has the power to run your entire product if you wish, or it can be connected via one of the supported serial protocols. The imp OS provides secure connectivity to the imp cloud. The imp cloud keeps your imp updated with the latest firmware, features online development tools, and provides cloud-side services for every imp in the field.”

“As with many cloud service organizations, development is generally free,” Bachiochi adds. “Once you’ve committed and have product rollout, the service will charge for its use. This could be a flat fee, a per-connection or data throughput fee, or a combination of fees. Basically you (or your customer) will have to pay to have access to the information, which pays for the support framework that keeps it all working.”

In his article, Bachiochi dives into a straightforward data-collection project to demonstrate how to use the imp in a product. The goal of his application was to log the activity of 220-V water pump and twin water softeners.  The project is the launching point for his comprehensive and detailed look at the imp’s hardware, software, and costs.

“It’s easy to design product hardware to use the imp,” he says. “There are two imp models, a card that can be inserted into an SD-type socket or an on-board module that is soldered into your product. Each version has advantages and disadvantages.”

Regarding software, Bachiochi says:

“Developing an imp application requires two parts to provide Wi-Fi access to your project: the device code (running in the imp) and the agent code (running on the imp cloud). The imp cloud, which is your connection to your device via the imp APIs, provides you with a development IDE. Web-based development means there is nothing else you need to purchase or install on your PC. Everything you need is available through your browser anytime and anywhere.”

Bachiochi also discusses the Electric Imp platform’s broader goals. While an individual can use the imp for device connectivity, a bigger purpose is to enable manufacturers to provide convenient Internet access as part of their product, Bachiochi says.

“The imp has two costs: The hardware is simple, it currently costs approximately $25 for an imp card or module. If you are using this in your own circuit within your own network, then you’re done,” he says. “If you want to roll out a product for sale to the world, you must take the next step and register for the BlinkUp SDK and Operations Console, which enable you to create and track factory-blessed products.”

BlinkUp, according to the Electric Imp website, integrates smoothly into apps and enables manufacturers and their customers to quickly connect products using a smartphone or tablet. The Operations Console enables tracking product activity and updating product firmware at any time, Bachiochi says.

The imp offers more than a low-cost way for DIYers and developers to connect devices to the Internet, Bachiochi says. A designer using the imp can save project costs by eliminating a microcontroller, he says. “Almost any peripheral can be easily connected to and serviced by the imp’s 32-bit Cortex M3 processor running the imp OS. All code is written in Squirrel.”

Bachiochi’s comprehensive article about his imp experience and insights can be found in the March issue, now available for membership download or single-issue purchase.
