About Us

Bluespectra helps organizations embarking on IoT projects to get the hardware side of their solution on track. Too often IoT projects are derailed by a disconnect between the needs of IoT innovation, and the pace at which hardware engineering and embedded systems can keep up. Bluespectra does this by providing products and services that are needed in early-stage IoT projects. These products and services are focussed on rapid, low-cost prototyping and iteration and actively managing the risk that exists with IoT hardware projects. Bluespectra works from reference designs and architectures, and works with capable partners and technology suppliers.


The rise of IoT has been driven by three things. The availability of platform infrastructure to process and store data, the availability of low-cost devices to gather data, and the ubiquity of connectivity to transmit data from the devices to the platform services. The software industry has largely concerned itself with the former - building the back-end services while largely ignoring the devices.

Modern IoT platforms have been rapidly assembled on the back of mature technologies and knowledge. Public cloud platforms are good places to store and process data cheaply. Certain technologies, such as complex event processing, which have been used for decades in the financial industry, lend themselves to processing of device telemetry. Big data analytics is perfectly suited to the analysis of large amounts of IoT data. With IoT, machine learning has an opportunity to gather large amounts of data for models and have a practical and significant impact on business. This means that IoT platforms, which appear to be fairly new, are based on proven technology and ready to process IoT data.

Putting devices into industrial machines, in the form of sensors, actuators, microcontrollers, and communications interfaces, has been in place for decades, and we are reminded that the hardware industry has been doing a form of IoT for a long time. From simple programmable logic controllers inside a single machine to factories with complex systems, existing suppliers and specialists are intimately familiar with the relationship between the physical world and the software world.

Bridging the existing physical world (the ‘things’), with the capability of modern software and connectivity (the ‘Internet of’), was never going to be simple and is, indeed, where the opportunity of IoT exists. OT (Operational Technology) and IT (Information Technology) need to move closer together. OT can learn from IT in areas such as security, where OT has traditionally used physical network isolation as a method to secure systems. IT has a lot to learn from OT such as making products that are reliable and safe, or performing firmware upgrades of devices in the field. A lot of progress had been made and standards, or at least agreed practices, are emerging for device identity, encryption, communications protocols, device management, and other important aspects.

It makes sense to business that since IoT platforms are ‘ready’ and a mature hardware industry exists that rolling out an IoT programme, while not easy, should be simple. Businesses are finding the opposite, where devices either do not exist or are tied to a (mostly legacy) proprietary stack that is too rigid for their needs. This creates a sense of disillusionment, where the real possibilities of IoT, which may be well understood, cannot be unlocked because of a never-ending series of technical issues, incumbent suppliers, and narrow (or non-existent) skills. IoT proof-of-concept projects start off with energy and enthusiasm, and a limited budget and timeframe to make their case. They become mired in hardware supply-chain issues, integration problems, and spiralling costs before a single measurement appears on a business users’ dashboard.

Bluespectra exists to bridge the gap between the physical hardware world and the IoT platforms with a specific objective to reduce the time, effort, and cost needed to get the first 100 devices out into the field. By including Bluespectra, businesses get a much better handle on hardware issues early on in the project, so that they can plan accordingly, and are helped to make the necessary adjustments in order to get initial devices developed and installed. By doing this, they have a shorter time to an end-to-end IoT implementation that can form the basis for further assessment and rollout.

Bringing modern engineering practices to the hardware side of IoT.

How we work

An existing IoT project will typically select a use case that has quantifiable business benefits and the ‘things’ that need to provide the necessary data. It is at the point of identifying the ‘things’ that Bluespectra steps in.

Scope device needs

An identified ‘thing’ may or may not have sophisticated electronics. It may already have sensors and a data acquisition module, or it may have nothing at all. The measurements required may not exist and will need to be fitted to the machine. Bluespectra engages with the machine engineers to identify what is practical to measure and what sort of sensors may be required. The collection and onward transmission of the data also needs to be understood and resolved.

Source devices

Due to the range of machines and hardware solutions in the field and in the market, it’s impossible to propose a single product that will solve all device needs. In some cases, nothing will exist and a set of sensors, a device, and a communication platform will need to be sourced from scratch, often within rigid constraints. In other cases, devices may exist, and are available from multiple suppliers – all with different costs, features and benefits. Bluespectra works with low-level hardware partners as well as incumbent technology suppliers that may already have a presence on the factory floor.

Adapt devices

Existing devices, even if they are newly sourced, will generally not fit in with a modern IoT architecture. Work needs to be done to adapt devices, through firmware changes or gateways, to support security, protocols, and device management required of modern IoT platforms. In the case where new devices are developed, they too need to be adapted to the environment. These adaptations include ensuring that the devices promote the strategic IoT objectives of the business, as well as being acceptable within the existing machine environment.

Manufacture devices

Devices that are not available off-the-shelf need to be manufactured. But, manufacturing a hundred devices is a very different process to manufacturing tens of thousands. Bluespectra supports an iterative approach to prototyping that allows for rapid and low cost manufacturing of devices that can be trialled within the IoT POC project. Month-long lead times and high up-front tooling costs intolerable when the business case has yet to be made. Bluespectra makes use of reference designs, short-run PCB manufacture, hand component assembly, and 3D printing to build device prototypes. Once devices are deemed fit-for-purpose, Bluespectra will work with manufacturers to setup a reliable and efficient manufacturing supply chain.

Test devices

Apart from testing that a device works as intended, devices need to be tested for the industrial environment in which they exist. Regulatory requirements need to be satisfied, certificates of conformance need to be developed, and devices need to be reasonably tested. Bluespectra facilitates the testing of devices with recognised industrial testing labs to ensure that it meets the needs of the environment in which it is to be installed.

Install devices

Devices need to be installed, replaced and repaired. In some cases, this may involve detailed documentation for existing on-site engineers. In others it may require a network of engineers that provide maintenance services over a large geographic area. Bluespectra works with customers or their partners in order to effectively manage the installation of devices in the field.


The IoT device space is large, complex, and filled with organisations that have great technology, products, and people. Bluespectra does not do all of the work itself, rather working with established organisations that have the necessary skills and track record of delivering IoT-capable hardware solutions.

Customer Benefits

IoT projects tend to focus, quite rightly, on the business benefits. An assumption is made that the devices will not be complex as the technology is already mature. One would think, for example, that a simple device to measure whether or not a machine is running is trivial. Buy an off-the-shelf product, put in a SIM card, plug it in and off you go. Unfortunately, the reality of IoT devices is not as trivial as it seems and projects can be derailed because not enough attention is paid to the detail of actually collecting data from a machine in the field.

In some cases, off-the-shelf IoT devices may exist, but they come with caveats. They may be expensive, where a complex high-end controller system is required. Or, they may require that the customer subscribe to the product vendors’ IoT platform, which creates early vendor lock-in which may not match with the customers’ yet-to-emerge IoT strategy.

Where devices do not exist, the choice of electrical engineer dictates the end solution. Existing electrical engineers are not familiar with modern IoT concepts, and proposed solutions may not match with a longer-term strategic need. Additionally, existing hardware development is fraught with long lead times, high setup costs, high specialisation and odd revenue models. Even with the right engineers and solutions, the practicalities of choosing what to install in a ‘thing’ and how to go about fitting in within the environment are not as simple as it may seem initially.
