What is Trending in Gas Detection and Sensor Technologies?

what is the best gas sensor

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

The clear trends across sensor modules and gas detection devices over the years have been focused on wireless, connectivity, accuracy, size, and ease of integration.  

Now, customers are looking for the latest and greatest in sensing technologies to integrate into applications such as scientific, medical, university research,  agriculture, aerospace, and much more. 

The evolution in terms of sensing has changed in regards to multi-gas solutions, size, durability, connectivity, and even speed. Much like purchasing or buying a reputable car, customers now want the same high-class features, bells, and whistles - in their newest technology. That includes sensors and gas detection technologies.

The improvements of technology in gas detection, now give the user peace of mind in knowing their sensor or device is compact enough for portability, durable enough for rugged environments, and easy enough to orchestrate, all with a simple touch screen panel or wireless feature. 

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 in the last two decades have shrunk sensors to the size of a coin, reduced the cost to under $100, and allowed for the design and manufacturing of compact, sleek modules you can fit in the palm of your hand with the ability to sense measurements at rapid speed and are packed with an abundance of capabilities. 

What is the best gas detection technology?

In terms of overall gas detection what distinguishes the best from the worst? Our engineering team decided to take a look at the technological advancements and key features that make these devices the utmost in terms of reliability, accuracy, speed, size, and application integration. 

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 insights into important aspects to distinguish choices and simplify your selection of a gas detection device or sensing technology.

Here are the top device specifications our customers ask about most often:  


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.  

In the world of gas sensors, you will notice that accuracy is normally given in 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 SprintIR®-R 100% CO2 Sensor.

The GC-0033 is one of the fastest CO2 sensors on the market, using NDIR technologies which can measure up to 100% CO2 concentration while taking 50 readings per second! This sensor's main competitive advantage is its response rate, which is 2.5X faster than the original fast response NDIR CO2 Sensor, SprintIR®-6S. 

Built on its unique patented LED technology the solid-state sensing module enables best-in-class speed and power consumption, making it an extremely popular and ideal solution for low power, battery applications, and consumers worldwide.

Additional industries that stand by the incredibly accurate sensor solution include pharmaceutical, modified atmospheric packaging, scientific research, and transportation.


Aside from accuracy, one important factor in sensing technology is 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 GrowFlux CO2 Microclimate Sensor.

The sensor features a smartphone, browser, or API access and precisely monitors carbon dioxide, temperature, humidity, and atmospheric pressure through the GrowFlux app for iOs and Android. This device is commonly used throughout horticulture environments.

Another key component in sensing technologies is durability. Continued testing and research in a variety of applications reveal how durable sensors are based on their integration in aggressive, and rugged environments. 

If you need the perfect sensing solution to be integrated for humid, aggressive, strained, or stressed environments, the K30 10,000ppm CO2 Sensor is a perfect choice. The K30 CO2 Sensor is a robust and solid-state design that has proven it will provide a longer life span in some of the harshest of environments.  


One area of specific interest in terms of sensing capabilities is the desire for high-speed measurements and fast response times.

Individuals from a variety of industries today often look for this feature to provide the user with instant, accurate, and repeated readings.

When discussing speed, we find that the one device for extremely effective fast measurements is the CM-1000 Multi-Gas Sampling Data Logger.

The CM-1000 is designed to simultaneously measure multiple gas concentrations through a sampling pump instantaneously and is used in a variety of industries due to its ability to measure up to 4 gas concentrations.

Applications include Scientific, Medical, Laboratory, Industrial, Fire Suppression, and Safety environments.

For those looking specifically to monitor 100% CO2 concentrations, the 100% Carbon Dioxide Sampling Data Logger is available, here.

Application Integration

One of the last areas we will discuss in this article is the trend towards easy integration with existing platforms and systems.

As an end-user, being able to have a gas detection technology with all of the bells and whistles, while being able to integrate into a variety of applications or environments is crucial. When one looks for the perfect sensing solution or "golden nugget" to provide such a broad span of features, there is no other comparison for the CM-7000 CO2 Multi-Sensor System

The CM-7000 was designed to protect customers and workers near stored carbon dioxide (CO2) and features a modern 8" touchscreen display panel, 12 unique sensor configurations, audible/visual alarms settings, and 4 distinct relays which meet OSHA/NIOSH standards.

The incredibly fast, accurate end easy to use device has made its presence known as a top choice for many individuals in restaurants, breweries, beverage dispensing, fast food establishments, and cultivation facilities.

Future Technology of Gas Detection

After taking a look at the main components of Accuracy, Connectivity, Speed, Durability, and Application integration, sensing solutions as we know them today will continue to evolve to meet customer demands and the everchanging requirements.

The future of gas sensor technologies will only continue to provide the end-user with completely new user experiences, exceeding expectations and futuristic technologies for years to come.
