8 Gas Detection Oxygen gas sensor sent into space


Students from the Leibniz Unversity of Hannover were selected to send their experiment into space to the International Space Station ISS. The space shuttle was launched on March 15th, 2023 with the Glücksklee experiment and EC Sense’s oxygen sensor on board.


The goal of the experiment is to study the symbiosis between clover plants and rhizobia bacteria in microgravity. The symbiosis between the plant and the bacterium leads to self-fertilisation. Gravity normally plays a major role in plant growth. Therefore, the team will test self- fertilization and growth under space conditions.


To this end, the plants will grow on the ISS and will be constantly monitored during this time with various sensors. Among other things, oxygen levels will be monitored with the TB200B-ES1-O2-25% gas sensor module from EC Sense.


The clover was chosen not only as a symbol of luck, but also because it belongs to the legume plant family, which also includes peas and lentils. These foods are rich in protein, which is necessary during long space missions, such as a mission to Mars, to provide astronauts with a source of nutrition.


EC Sense take great pride in supporting the scientists of the future on such an important forward-looking topic! For More Info, email:

Harnessing the power of landfi ll gas and biogas with precise and dependable gas sensor technology

Landfi ll gas (LFG) and Biogas are similar in creation process and composition – and for the fact of representing both a resource and a hazard, with appropriate monitoring and management tipping the balance between the two extremes.


N.E.T. high-volume IRNET sensors are the ideal fi t for Landfi ll gas (LFG) and Biogas applications due to: • 0…100% detection range for Methane (CH4


) and Carbon dioxide (CO2 )


• rugged stainless steel built and protective coatings to ensures resistance to the acid gases associated with the application • available in ATEX or IECEx certifi ed versions for maximum safety and use in classifi ed areas • our exclusive Dynamic Range technology ensures optimal performances and unprecedented accuracy


Biogas can be produced from various raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste while LFG is the product of anaerobic degradation of the organic fraction of solid urban waste within a Landfi ll. These gases are primarily methane (CH4


) and carbon dioxide (CO2 hydrogen sulphide (H2 ) – both of which are greenhouse gases – and may have small amounts of S), moisture and other volatile organic compounds (VOCs).


Capturing biogas and LFG avoids the release into the atmosphere of environmental-harmful compounds. In terms of global warming potential, methane is over 25 times more detrimental to the atmosphere than carbon dioxide. Landfi lls are esteemed to be the third largest source of methane in the US.


Because of the toxicity and fl ammability of these gases, monitoring techniques have been developed to decrease the risk involved. Detectors are used to measure methane as well as CO2


More and more instrument manufacturers around the industry are choosing our sensors for continuous monitoring systems and safety-related detectors.

out. In the U.S. it is mandatory that large landfi lls install gas collection and control systems, which means that at the very least the facilities must collect and fl are the gas.


Is thermal imaging the key to faster, safer and more effi cient


fi re fi ghting? Towergate Insurance has spoken about the importance of thermal imaging cameras and how it is the future of fi re protection in the UK. The company has highlighted government research which shows the high number of false alarms generated by automatic fi re alarms. Emergency services attended no fewer than 238,885 false alarms in the UK between April 2022 and March 2023.


Many workplaces install fi re alarms, extinguishers and fi re doors and carry out regular risk assessments and equipment maintenance and believe they have the problem covered. However, in the UK, there are around 22,000 workplace fi res every year. That is an average of 423 fi res per week in the workplace alone.


Simon Broome, Risk Manager UK Regions, Towergate Insurance said: “Many common commercial fi re prevention strategies are missing a critical element, the fact that most of their procedures are only useful when there’s already a fi re in progress. What we are interested in is focusing on genuine fi re prevention and thermal imaging cameras offer a fl exible and adaptive solution.


“Thermal imaging cameras let people see what their eyes cannot. They create an image from heat and can continuously monitor heat levels in commercial buildings and highlight areas of heat activity. They can even provide a thermographic image of what is going on inside a machine, providing advance warning of rising heat levels and the need for maintenance.”


This equipment can also be of immense help to the emergency services. When a major fi re broke out in a supermarket in Norfolk, in September 2023, fi refi ghters used thermal imaging to check for hotspots so that they could tackle the fi re more effectively. Even more recently, during a warehouse fi re in Essex caused by lithium batteries exploding, fi refi ghters were able to accurately pinpoint where in the building they needed to focus their efforts in order get the fi re under control as quickly as possible.


Simon Broome, added: “In 20 years’ time, people will look back at their current fi re prevention and protection strategies, which are largely based around a fi re already having erupted and consider them to be archaic. Thermal imaging cameras fi ll the space that’s missing in modern fi re procedures, working not only preventatively but also in actively saving lives. It is the future of fi re prevention now!”
