Excess carbon dioxide levels can also cause drowsiness, headaches, and many other issues – none conducive to good health. Since we tend not to consider carbon dioxide levels, we rarely consider how they can impact us – however, they can affect us significantly. Aranet4 display app: This solution projects CO 2 measurements onto larger screens – like monitors, TVs, etc. It’s ideal for displaying metrics in an easy-to-understand, public way. Some features can be controlled from the app while other are only accessible via dip switched that are under the cells in the battery compartment.

De Aranet4 combineert de drie belangrijkste parameters (CO2, temperatuur en relatieve luchtvochtigheid) om realtime het binnenklimaat te monitoren. De Aranet4 werkt met de gratis 'Aranet4' app (Android/IOS). Via de app kun je tal van instellingen (o.a. meetinterval, alarm) aanpassen, de CO2 sensorhandmatig kalibreren in de buitenlucht en de metingen terugkijken overde laatste7 dagen. Je hebt hiervoor een smartphone of tablet nodig!Aranet4 HOME izmanto labāko NDIR (nedispersīvo infrasarkano staru) sensoru tehnoloģiju, lai visprecīzāk noteiktu oglekļa dioksīda (CO₂) līmeni. Pateicoties e-tintes displeja tehnoloģijai, akumulatora darbības laiks (2xAA) ir līdz diviem gadiem. Wireless connectivity: Wires are problematic. It’s much more convenient to have a sensor automatically send data along to the cloud and mobile app, rather than drilling, installing, and continually dealing with stationary cables. Battery life is similarly incredible. While it varies based on the frequency of readings, the minimum battery life is around eight months. This is with updates every 1 minute, an option that most people won’t enable. However, if you lower the readout times to once every 4-minutes and use lithium batteries, the device can have a four-year lifespan! Understandable graphs: Data gathered by the Aranet is compiled in a colored graph that makes representation simple.

Well, yes and no. The concentrations of carbon dioxide we are usually exposed to are unlikely to cause long-term damage. For that to occur, we must be exposed to severe carbon dioxide concentrations for a long time. For best accuracy, recommended operating range is 10°C to 40°C (50°F to 104°F) and 20% to 60% RH (non-condensing). The device is portable, simple to install, easy to operate and lets you know when the monitored levels have become unhealthy.Thanks in large part to COVID-19 related studies on virus transmission 3, growing numbers of people have become aware that poor air quality directly affects their respiratory health, productivity, cognitive function, and wellness. However, it’s difficult to understand the cleanliness of one’s surroundings without a specialized monitoring device. While the Aranet4 is fully operational on its own, additional capacities are available once connected to a smartphone via Bluetooth. Enjoy these, and several other functionalities when linked to the application: Monitoring carbon dioxide levels and acting on the information is incredibly beneficial. Like indoor air pollution monitors, which monitor the particulate matter and VOCs, I recommend a portable device such as the Aranet4 Home for anyone wanting to improve the quality of the air they breathe. It really can change how you live and especially how you feel. By default, Aranet4 Home will update itself once every five minutes. This is adjustable, and the user can specify if they want readings every one, two, five or 10 minutes. Again, it’s worth noting that an increase in measurement frequency will decrease battery life. Although cheaper monitors may use different types of sensors, none of these is as accurate as an NDIR sensor – many aren’t accurate at all. Most other sensors are electrochemical and are known to be less accurate. Unfortunately, some manufacturers have begun to label their devices as NDIR when they are not. This has caused a lot of mistrust within the space.

Overall, the Aranet4 Home (and PRO) are very accurate devices and among the most precise on the market. Especially compared to cheaper NDIR-equipped products, the Aranet is more accurate and will provide accurate readings for many years. The team at Aranet was kind enough to send me an Aranet4 Home for review. Over the past year, I’ve used the device extensively. I’ve travelled with the monitor, taking it on planes, buses, and into malls. I’ve also used it at home and during walks in the park to test the accuracy of the readings against atmospheric air. Perhaps the most critical question regarding CO2 monitors is ‘What is the accuracy?’. Accuracy is the most significant difference between cheap and pricier alternatives within this space – it’s also what drives the price of the Aranet4 Home up.However, it’s also essential to have an accurate device – not only are you not getting accurate information with some cheaper alternatives, but you could be being misled entirely.

Aranet4 HOME is an innovative battery-powered stand-alone bluetooth sensor.

Aranet showed CO2 in the range of 420-426ppm for three readings in a row. This is incredibly accurate, and while I’m not sure what the actual ambient concentration was then, it is very promising. This is exactly the concentration you would expect to see in an ambient environment. Despite the price tag, this combination of factors allows me to recommend the Aranet4 Home. It offers a complete experience and worked flawlessly throughout my time using it. While there are a few minor changes I would like to see, these are to fine-tune an already great experience.

It’s also worth noting that there has been a substantial update in the year I’ve had the Aranet4 home, adding a few features to the device. This makes it clear that the team behind Aranet is invested in their device and ensuring it is the best it can be – unlike many other manufacturers who will happily leave their devices behind in favour of releasing a new one. While I don’t know if we will see future updates, I am confident that SAF Tehnika will keep supporting its device. As a final note, I had a friend who lived in a small apartment and complained about constantly feeling tired at home. I mentioned it could be carbon dioxide and recommended he open the windows regularly to see if it would help. A few days later, he returned to me and said it was life-changing – he felt far fresher and more awake than he had at home in months.The Aranet4 Home also has automatic calibration. This allows the device to calibrate itself automatically every 30 days and can be switched on and off via a small switch located under the double A batteries used to power the device. While this might sound like a handy feature, I recommend caution regarding automatic calibration on any carbon dioxide monitor. There’s no VOC or PM2.5 detectors here, but the on-board electronics use a special type of ‘NDIR’ sensor for CO₂ measurements… Some drift can be found over time in the temperature, humidity, and atmospheric pressure sensors. However, the drift is generally minimal and shouldn’t impact your device usage – even after five or more years.
