What Are the Best Air Quality IoT Devices?

Are you interested in making the best possible investment for your business? And, more importantly, do you want to know what IoT devices are the most important for monitoring indoor air quality? Whether it is your home or office, many companies worry about the health of their employees.

In today's technology-driven world, some companies also depend on their employees, not just working but feeling happy and healthy at work. A balanced indoor air conditioner can provide a pleasant environment that is ideal for productivity and better concentration. But how do you know if your air-quality monitoring system is helping you accomplish these goals? The answer lies within your IoT device review.

How Do Air Quality IoT Devices Work?

Air quality IoT monitoring sensors are small machines that measure the concentration of certain chemicals in the air. They do this by taking samples and analyzing them. This can be done with any type of IoT sensor, whether it is a simple coin cell battery-powered sensor or a high-tech gas chromatograph mass spectrometer.

Once these IoT sensors have finished collecting their data, they send it to a computer via USB or Bluetooth. You can then use this information to see if you need to act—for example, if your air quality is low enough that you should consider wearing a mask or even going outside for some fresh air! 

To use these devices, all you need is an internet connection, some way to get data from your device (like Google Sheets), and an application that will allow you to view all your data in one place.

An air quality IoT monitoring device can be used for anything from measuring indoor air quality to tracking outdoor air quality. It is important to note that some devices can measure both indoor and outdoor air quality at once—a feature that makes them particularly useful for businesses that need to ensure their employees' safety while working indoors.

Why Is It Important to Monitor Air Quality?

Air quality monitoring is important for several reasons. It can impact our health, and it can affect the environment.

One of the main reasons air quality is important to monitor is that it impacts your health. When you breathe in air with elevated levels of carbon monoxide, for example, you could develop symptoms like dizziness or nausea. Air pollution can also cause respiratory problems like asthma or bronchitis.

Air quality can also affect the environment if you release too much oxygen into the atmosphere. For example, when oil spills occur at sea level, they send out a plume of oil that affects marine life in turn—and this has consequences for human health as well, as some people are affected by this as well (like those who work at sea).

It is crucial that we track the situation as air quality can vary from one location to the next at various times of the day. That way, we can pinpoint the worst polluted areas

and take corrective action to guarantee that everyone is breathing the healthiest air possible. 

Different Techniques for Monitoring Air Quality of a Place?

The diverse types of monitoring the air quality of a place are:

1) Environmental monitoring, which is done to assess the health condition of an environment.

2) Industrial monitoring, which is done to assess the quality of products produced in an industrial unit.

3) Meteorological monitoring, which is done to study weather patterns and climate change.

There are numerous methods for taking air samples to determine the level of pollution.

i. Diffusion Tubes

Without the use of any electrical power, diffusion tubes can purge the atmosphere of a certain type of air pollution. In most cases, the monitoring period for a diffusion tube would continue for somewhere between two and four weeks. It is the only way to determine the level of pollution that was found; therefore, the tubes must be analyzed in a laboratory.

The diffusion tube approach has the benefit of being cheap and easy to implement. Detailed Assessments’ automated monitoring system is useful for screening and baseline research. One drawback is that its efficacy against certain contaminants is still up for debate. This must be checked out in the lab. 

ii. Semi-automatic Monitoring

The air in the room is filtered by an analyzer, which runs through a new filter every day. When the filters have done their job, they are collected and delivered to a lab where the levels of pollution may be determined.

This monitoring method's strengths lie in its low cost, simplicity of implementation, and dependability. Archived data is obtainable through UK-based networks. One drawback is that many approaches require a lot of manual labor. Testing in a lab is essential. 

iii. Observation of selected points automatically

The concentration of the selected gas is determined by passing ambient air through an analyzer. Pollutant levels are tracked continuously by automated sites. Instantaneous viewing is possible because the site's data is being transmitted straight to the computer.

The high-resolution data that may be obtained with this technology is one of its main advantages. It is feasible to acquire information online. Give information that can be resolved to a path or range. The downside is that it is pricey. A skilled operator is needed. The price of upkeep and repairs on a regular basis. 

iv. Long-distance/optical monitoring from a distance

Pollution between a light source and a detector, which are located at various locations, can be detected using this monitoring technique. This sampling method allows for continuous monitoring and measurements. The analyzer's data can be transmitted straight to your personal computer.

The advantages of this strategy come from the presence of relevant nearby sources. It is feasible to measure multiple factors at once. Data has one major shortcoming in that it cannot be easily compared to discrete quantities.


Best Devices to Check Air Quality at Home


The sensor is a complete LoRaWAN monitoring system. It has a precision of +/- 40 ppm for measuring CO2, which is a nice bonus.


In addition to measuring temperature, moisture, sunlight, CO2 levels, TVOC, air pressure, and mobility, the AM307 is also a compact interior ambiance tracking sensor.


This is a cordless indoor environmental quality monitor. The frequency of transmission and the interval between measurements are both flexible.


Its purpose is to make living and working environments more pleasant. Installation is simplified thanks to its small footprint, allowing sensors to be placed closer to the people whose data they are collecting.


By regulating and monitoring CO2 levels and people's presence, safer and healthier indoor environments can be created, protecting students, and workers, and achieving regulatory standards for air quality. Indoor closed areas only allow entry to authorized individuals, and their presence is controlled to avoid overcrowding.


To lessen the likelihood that viruses like COVID19 may propagate within a building, manufacturers have released a new Internet of Things Comfort Sensor. The Comfort Sensor is a battery-operated air quality monitor that communicates its findings through LoRaWAN (or Narrow Band IoT) (NBIoT).
