What is Trending in Gas Sensor Technologies?

As a company that is recognized as the "leader in gas detection" we often get asked the question, "What has changed in terms of gas sensing technologies over the years and what should I look for?"

As each year continues to bring more innovation across the industry, our team wanted to discuss the recent trends focused around wireless connectivity, multiple gas sensing, accuracy, and sensor lifespan. 

In the past, customers seemed to be looking for the latest in sensing technologies focused on size and ease of integration alone. Recently, customers are looking much more closely at sensing technologies in order to easily integrate them into unique applications such as indoor air quality (IAQ), healthcare, agriculture, safety, university research, and much more.

Much like purchasing or buying a reputable car, customers now want the same high-class features, bells, and whistles in the latest gas sensing technologies.

That includes sensors and gas detection devices, too.

The improvements in technology now allow for the user to have full peace of mind in knowing their sensor is able to accurately provide measurements, analyze across multiple gases, and is easy enough to orchestrate, all within a simple touch screen panel or smartphone app. 

The real game-changer in terms of present-day gas detection solutions is this futuristic ability to now be able to monitor gas concentrations with a more modern-day approach. Sensors used to be enormous and cost a lot, too. 

Advances over the last few decades have downsized sensors to the size of a coin, reduced the cost to under $100, and allowed for the design and manufacturing of the compact, sleek modules you can fit in the palm of your hand today.

Not to mention these sensors have the ability to sense measurements at rapid speed and are packed with an abundance of capabilities and features. 

What makes the best gas detection device?

In terms of overall gas detection, customers often want to understand what distinguishes the best from the worst? Our engineering team decided to take a look at the technological advancements and key features that currently make certain devices standout in terms of accuracy, multiple measurement, lifespan, and wireless connectivity.

Whether you need to detect CO2, O2, CO, or any other gas concentration finding the most effective, accurate, and reputable technology to do so, is not always an easy task.

Our team is here to help simplify your search by offering some educational insight into the important aspects of sensing in order to distinguish and simplify your choice of a gas detection device or sensor.

Below, we have categorized the top gas sensor technologies by important capability and those that our customers ask about the most frequent.  


One key component in a gas detector is its accuracy. Customers tend to look for accuracy as it is used as a performance specification which often combines the effects of conformity and repeatability.  

Simply put, accuracy describes how closely the indicated value represents the actual measurement being monitored while taking into account all possible sources of error that could be relevant in an application.

In the world of gas sensors, you will notice that accuracy is normally given two formats: +/- ppm and the percentage (%) of the measured value. The +/- ppm reading is an indicator of the range for an accurate reading. The percentage of the measured value is generally thought of as the "worst-case scenario" for the accuracy of that sensor.

In terms of top solutions for accuracy, and reliability, we turn to the K30 FS Fast Response 10,000ppm CO2 Sensor

The SE-0117 is one of the fastest CO2 sensors on the market, using NDIR technologies which can measure up to 10,000ppm CO2 while taking readings 2x per second! 

This sensor's main competitive advantage is its fast response rate, making it an ideal low-cost solution for individuals who want to integrate CO2 sensing into applications like modified atmosphere packaging (MAP), occupancy detection, or anywhere rapid data sampling is needed.

Built on best-in-class NDIR technology, this sensor module is extremely popular across CO2Meter customers and also has a lifespan of more than 15 years.

Additionally, this sensor module can be connected to a sensor development kit for those who want to gain further analysis and measure or graph the gas concentration levels over time for data logging purposes.


Aside from accuracy, another important factor in sensing technology is how to effectively read and collect data whether through traditional analog or digital outputs or connectivity to the cloud or wireless monitoring.

With the ability to remotely monitor gas concentrations "on-the-go", customers are able to gain critical measurements and updates, all from a smartphone or PC. CO2Meter customers or anyone looking for cloud-based monitoring and data logging capabilities continue to lean towards the Aranet4 PRO Indoor Air Quality Monitor.

The device features a sleek, modern, wireless design and can accurately detect CO2, temperature, relative humidity, and barometric pressure - all from the Aranet4 iOS or Android app.

This device is most commonly designed for monitoring indoor air quality across homes, universities, office buildings and commercial spaces; or anywhere CO2 levels should be monitored for occupant comfort.

Multiple Gas Detection

Another key component sought after in gas sensors is the ability to monitor across a wide range of multiple gas concentrations. Continued application advancements across a variety of industries have opened a need to not just monitor one gas but several gases, simultaneously, in any one given environment.

With the flexibility to monitor up to 64 sensor configurations across CO2, CO, O2, and CH4 gases - the most advanced portable detector that most customers find as an ideal solution is the Multi Gas Sampling Data Logger.

Additionally, this device also utilizes a micropump and draws samples into the sensing chamber allowing each sensor to take incredibly fast and accurate measurements. The CM-1000 can be used across a wide range of industries such as Fire Suppression Testing, Medical, Scientific, and Industrial processes.


Another area of specific interest in terms of sensing capabilities is the desire for not only high-speed measurements and accuracy, but selecting a technology that will ensure a long lifespan towards the future.

Individuals from a variety of industries today often look for a device or sensor with a long life to ensure that the device can work correctly at all times given the critical nature of many gas detection environments.

When discussing lifespan, we first note the need for specific gas concentrations and then discuss the sensor method for the particular gas device or gas sensor. While there are multiple gas sensing technologies available, the life expectancy of a sensor is most commonly linked to the technology it holds.

For reference a typical lifespan of an electrochemical sensor can usually be between 2-3 years, whereas a nondispersive infrared sensor can last anywhere from 15 years or greater. 

For those interested in understanding what features can directly affect the sensor lifespan we have included the following:

  • Relative Humidity
  • Temperature
  • Cross-Sensitivity to interfering gases
  • Vibration or Impact
  • Cleaning Agents
  • Contamination of environmental conditions (dust, debris, sand, pests)
  • Exposure to poisoning when sensor is not powered

Application Integration

Lastly, a final critical feature that we will discuss in this article is the trend towards ease of integration with existing platforms and systems.

As an end-user, being able to have gas detection technology with all of the bells and whistles, while being able to easily integrate into a variety of applications or environments is crucial.

When one looks for the perfect sensing solution to provide such a broad span of features, there is no other comparison for the CM-7000 CO2 Multi-Sensor System
