Internet of Things (IoT) technology is enhancing our lives, helping to improve the environment and transforming almost every industry.

When you think of IoT, you may think of fitness trackers, smart lighting and intelligent thermostats – but IoT is so much more – with endless applications in business and society.

In this short article, I shall provide a brief introduction to IoT and explain how IoT is helping to drive positive change with regards to pollution and our environmental habits. I shall also outline why the Isle of Man is well-positioned to emerge as a leader in this exciting technology ecosystem.


An IoT solution has four main parts:

  • Sensors. Each IoT device features many sensors, each one taking readings or recording an event. The devices typically run on batteries and can be powered by solar or other renewable sources.
  • Connectivity. The data created by the sensors is transmitted wirelessly to a central point, such as the cloud or data processing servers.
  • Data Processing. After receiving the data from the IoT devices, the data is stored, analysed, and acted upon. Processing may include manipulation, machine learning and artificial intelligence (AI). Microsoft and Amazon have pre-built platforms for IoT applications, but Isle of Man datacentres are also a perfect location for IoT data.
  • User Interface. After the data has been collected, transferred and processed, the results will be visualised on charts, dashboards or interactive apps.

New IoT start-ups have sprung up around the world; solving old problems with modern technology, out manoeuvring the larger, entrenched and less nimble companies, carving out new niches in the process.

Established, industry-leading organisations, recognising this threat, began retrofitting advanced sensors into existing product lines – bringing their technology into the 21st century.

Finally – Governments and local authorities are turning to IoT to assist them in solving challenges with healthcare, transportation, pollution, and air quality. Most recognise the important of using data to establish baseline, to measure progress and to prioritise activity – which IoT can assist with.

It’s all about value. Whether the goal is to save money, make money, or improve outcomes – whether those outcomes are health, environment or economy related.

Air Quality

One of the most prominent applications of IoT technology is air quality monitoring. IoT enables you to measure air pollution using inexpensive sensors and in a real-time manner.  

According to the World Health Organisation (WHO), Air pollution is the 4th biggest killer in the world after smoking, high blood pressure, and bad diet. A recent study published in the New England Journal of Medicine highlighted the link between moderate increases in pollution and particulates, and higher mortality rates.

For these reasons, it is no surprise that responsible Governments and local authorities are turning to technology to help understand the problem, develop policy, and safeguard their residents.

  • The cities of Birmingham and Bradford are using IoT technology to measure air quality in real-time, complementing their existing fixed monitoring stations with IoT, and supporting their goal of improving air quality for the city’s residents.
  • In Togliatti (Russia), the air quality of children's playgrounds is monitored using IoT and blockchain technologies, with the results available online, to both the public and Government.
  • Scotland has LAQM (Local Air Quality Management) guidelines that define how councils must review and assess air quality in their regional area. IoT is helping meet the LAQM requirements, but it has also led to a significant economic opportunity for Scotland.

The Scottish CENSIS innovation centre, has supported dozens of IoT technology trials throughout Scotland, using a national IoT network. The software, devices and solutions, in areas such as air quality monitoring, are now exported and sold throughout the world.

Most districts and councils in the UK and Scotland publish their real-time and historic air-quality measurements online, which not only educates the public, but it helps shape policy and planning decisions. IoT has driven down the cost and complexity of air monitoring solutions – making this extensive monitoring more commonplace, accessible and cost effective.


With wellbeing, climate change and air pollution being hot-topics, it is no surprise that many prominent applications of IoT apply to schools and colleges. These applications don’t just focus on outdoor air quality, but the indoor environment.

In 2016 a team of Harvard researchers discovered a 15% decline in cognitive ability when indoor CO2 levels were 950 ppm (parts per million) and a 50% decline at 1400 ppm. For reference, the average CO2 levels of ambient air are 250-400ppm.

When one UK school measured CO2 levels during a double lesson, they discovered CO2 levels as high as 2,300ppm – which would cause a dramatic reduction in concentration, mental ability, and focus.

With this growing body of evidence, many schools are deploying indoor air sensors throughout their classrooms and corridors to monitor CO2 levels, but the sensors are also used to detect vaping, tobacco and shouting! These inexpensive sensors are 50% smaller than your average smoke alarm and run on AA batteries.

Some prominent building standards such as the American Well v2 standard recommend the monitoring of indoor air quality to enhance health and wellness, given the proven link to concentration and productivity.

In an age where there is so much emphasis on educational performance – the solution to better educational grades could be a case of opening the window!

Water Quality

In February 2018, the Environment Agency in the UK published the “State of the Environment Report – Water” which reported a gradual decline in the condition of English rivers.

Over 86% of Rivers throughout England failed to achieve functional ecological status. The reason for this poor quality was chemical pollutants.  The presence of these chemicals may be due to run-off, agriculture, manufacturing, landfill and other sources of pollution.

IoT offers an inexpensive means to test water quality on a large scale. Smart Water is an umbrella term for when IoT and software are applied to applications involving water.  IoT sensors have been deployed throughout entire river networks, from estuaries to tributaries, to record end-to-end water quality.

Monitoring Drinking water, protecting the ecosystem and identifying environmental offenders are just some applications of IoT technology.

Greener Future

All the examples mentioned in this article rely on accurate, timely data. The primary application of IoT is to use sensors, to take measurements, to produce valuable data. In the case of the environment, this data serves as the foundation of any initiative focused on improving the environment, enforcement, reducing pollution or encouraging positive change.

The ability to measure and monitor at scale not only improves insights and intelligence but having a reliable, timely baseline - leads to more insightful decision making, more effective policy and strategy, and helps focus attention on the future.

Isle of Man

When you consider the different components of an IoT solution and its applications in the real world, the Isle of Man is an excellent location for IoT:

  • IoT is a global market, projected to grow to about $520 billion by 2021. IoT technology can be designed, developed and proven in the Isle of Man – before exporting to the rest of the world. After all, there are 520 billion reasons to do so.
  • The Island has exceptional mobile coverage and two excellent mobile operators, both of whom are willing to trial emerging technologies.
  • With several datacentres and reliable connectivity to UK Cloud providers, IoT deployments on the Island have several options to store and analyse their volumes of data.
  • The facilities and expertise at the UCM provide the ideal balance of practical and digital skills, both of which are needed to develop IoT solutions in the real world. Once learned in the Island, these skills can be exported or provided remotely to others.
  • The Isle of Man is home to several diverse industries, and we all recognise the Isle of Man’s natural beauty, coast and countryside. The variety of applications available on the Isle of Man position it as an ideal location to design, develop and deploy IoT technologies.
  • IoT tech-trials represent a unique opportunity for the Island, particularly considering its many strengths, diverse industries and its UNESCO status.

IoT is an exciting technology and one which provides an opportunity for any business or industry to re-invent itself.  While this article has focused on environmental monitoring, the possibilities are endless.

In many ways, technology is the easy part – it is the in-depth industry knowledge and ability to identify a better way of doing things where the opportunities sit.
