What we can measure


Download Sensor Datasheet

The Think Air Monitor is a low cost Air quality node capable of LoRaWAN, 3G, Wired or WiFi connectivity, equipped with a Multi-sensor modular unit that can integrate into existing Think Air networks.

The modular node offers extremely accurate PM10, PM2.5, CO1, NO2, C2H6OH, H21, NH31, CH4, C3H8, C4H10, temperature and humidity readings confined within a small powered unit.

The unit has colocated with local authority controlled AURN monitoring networks to ensure the values displayed have correlation that parallels that of the current government reporting network. 

Detectable Gases

  • Carbon monoxide CO 1 – 1000ppm
  • Nitrogen dioxide NO2 0.05 – 10ppm
  • Ethanol C2H6OH 10 – 500ppm
  • Hydrogen H2 1 – 1000ppm
  • Ammonia NH3 1 – 500ppm
  • Methane CH4 >1000ppm
  • Propane C3H8 >1000ppm
  • Iso-butane C4H10 >1000ppm

Understanding The Problem

CO2 is produced when people breathe. Each exhaled breath by an average adult contains 35,000 to 50,000 parts per million (ppm) of CO2 – 100 times higher than is typically found in the outside air (OSA).

The CO2 concentration in an occupied indoor space indicates if the building’s air exchange balance is appropriate – that is, if the optimal amount of OSA is being mixed with air that has been circulating in the building


PM2.5 – why we need to measure

Despite emissions falling annually, around 40% of NO2 and a third of PM2.5 still comes from industry and traffic – particularly in urban areas.

So far so concerning, but you may be surprised to know that our workplace and personal behaviours contribute to even greater levels of NO2 and PM2.5 – the latter of which is particularly worrying.

Why?

Because the smaller the particles, the more damaging they can be.

PM2.5 is so small that it can slip past our body’s defences and settle deep into our lungs and bloodstream – leading to both acute, short-term health issues and chronic disease.

What’s more – many of today’s industrial processes are adding to the problem. Manufacturing, construction, and power stations are key contributors to our high NO2 and PM2.5 levels.

It’s time to Think Air

Developed by science-based innovators and experts, the Think Air team is at the forefront of air quality monitoring and measuring in the UK. They're also the team shaping the Government's air quality policy on both a local and national level.  

But now, for the first time, they’re also helping organisations like yours to do their part, too.

The quality of the air around us isn’t just a local issue – the PM2.5 that we breathe in might often come from many miles away, which means we cannot rely solely on modelled data.

Until now, it’s been difficult and costly to measure external air quality. Think Air’s cutting-edge sensors and software make real-time monitoring easy, affordable, and accessible.


How much CO2 Is too much?

Current ventilation guidelines, such as those from the Society of Heating Refrigerating, and Air Conditioning Engineers, recommend that indoor CO2 levels not exceed the local outdoor concentration by more than about 650 ppm. Good practice indicates that the ASHRAE Standard 62.1 target CO2 level in indoor air is about 1,030 ppm given the outside average of 380 ppm. It is important to adhere to these guidelines.

The performance of individuals in schools and offices with elevated CO2 concentrations can be affected because occupants may become lethargic and drowsy. Additionally, as CO2 builds up, so do other indoor air contaminants, which increases occupants’ exposures to irritating, distracting and potentially unhealthy gases and particulates

The Benefits to your Business of Think Air

Corporate social responsibility (CSR) has become crucial for organisations looking to build trust, boost brand image, and increase profit – and Think Air is leading the way for all three.

A recent Clean Air Fund study found that 3 million working days are lost each year because of air pollution. Poor air quality has also been linked to lower productivity and employee performance.

But monitoring and managing external air quality lets you create a better environment for both your stakeholders – and your wider community.

Monitoring – and improving – air quality helps you to minimise employees’ exposure to harmful air pollutants. This, in turn, has been linked to higher performance, greater productivity, and a decrease in sick leave.  

Long-term air quality monitoring helps you to identify patterns that can be used to inform policies and practices to drive down pollution.

There’s a direct link between air pollution and climate change – so being at the forefront of air quality monitoring shows employees, investors, and communities that you’re committed to greener business. 

Think Air also provides background data for organisations looking to see the impact of their working conditions – alongside general background levels of air pollution.


How Think Air works

Think Air is the largest non-government particulate monitoring network in the UK.

It brings you the live data that will transform your organisation’s environment.

Easy, accessible, and affordable, Think Air’s cutting-edge air quality (AQ) sensors measure and monitor PM2.5 levels to give you a clear view of the air around you, what’s impacting it, and where in the world it’s coming from.

Data is collected by the Think Air cloud-based database and presented to you in easy-to-understand dashboards.

You can access it anywhere, from any device, and download reports and charts in both PDF and Excel formats.

The entire platform works across all devices and networks, including Windows, IOS, and Android.

External networks can also be linked to indoor monitors to give you an even more comprehensive view of your local air quality.
