Product Information

Do you have any thoughts or experiences with Aranet4? If so, please feel free to share in the comments below! Alternatively, if you have any questions about the device, please ask, and I will do my best to answer. Thanks for reading! Mēs pavadām līdz pat 90% sava laika telpās, kur katru minūti izelpojam oglekļa dioksīdu jeb CO2. Paaugstināta CO2 koncentrācija var būtiski ietekmēt mūsu veselību un labklājību. Atrodoties telpā ar CO2 koncentrāciju virs 1000 ppm (par miljons daļām), var rasties nogurums, galvassāpes, reibonis un citas ilgstošas veselības problēmas. 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! CO2 līmenis tiek parādīts, izmantojot "luksofora" krāsu indikatorus, kas kopā ar skaņas signālu brīdinās par gaisa kvalitātes pasliktināšanās situācijām. 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.

For this reason, automatic calibration should only be used if you regularly take the device outside. Aranet Tech Support suggests the minimum should be eight hours every month, which doesn’t need to be done simultaneously. As long as the cumulative time the Aranet4 spends exposed to outdoor air is eight hours monthly, automatic calibration should be reliable. The average person takes about 22,000 breaths every 24 hours. 1 Each one of these inhalations can bring a variety of unwelcome substances into the body – potentially making colossal impacts on health. 2 Battery life: This device contains a quality e-ink display and the device itself can function for up to 10 years after activation, depending on how often the device updates measurement data. Readings can be set to one, two, five, or 10-minute intervals between updates in the mobile app. Everything about the app interface is polished. Setup, firmware updates, regular usage, power-user features, you name it. 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.

Aranet4 is an innovative battery-powered stand-alone wireless sensor for monitoring CO2, temperature, relative humidity and atmospheric pressure at home, school, office or another indoor environment. The device is portable, simple to install, easy to operate and lets you know when the monitored levels have become unhealthy. These next couple of images are where things begin to become interesting! Both of them show high concentrations of CO2, which also indicates poor ventilation. In the case of the first image (taken during a full flight), the reading also indicates a 4x transmission chance of COVID-19 compared to ambient CO2 levels. The Senseair Sunrise sensor is a single sensor – the humidity, temperature, and atmospheric pressure sensors included in Aranet4 are separate from the CO2 sensor. This is a different approach from sensors such as those offered by Sensirion, which includes all three sensors on the same chip. Through the app, the Aranet4 also has a very cool feature that was only released in 2023 – the ability to take an on-demand reading. This is incredibly handy and allows the user to force the device to update its reading. This process takes only a second, and it means you can set the device to take readings automatically every five or 10 minutes while force-updating when the situation calls for it. So far, this feature appears to be unique to the Aranet4. This change of mind return policy is in addition to, and does not affect your rights under the Australian Consumer Law including any rights you may have in respect of faulty items.

Users can adjust measurement intervals, buzzer sounds, Bluetooth range, CO2 indication mode (what colours indicate what concentration), and CO2 calibration in the app settings. Users can also toggle between temperature units, pressure units, and date formats to keep the device easily usable for everyone. As for the lifespan of the Aranet4 Home, provided the device is treated well and doesn’t get damaged, it should be able to provide accurate readings for many years. In addition, the CO2 sensor can be recalibrated and, therefore, suffers from no sensor drift. The Sunrise sensor is supposed to have a 15-year lifespan. While I doubt you will get 15 years out of an Aranet4, the device is made to last. It appears as though some Qingping Air Quality Monitor devices use different sensors. Some use Sensirion (SD30) sensors, while others use Senseair sensors. Recalibration: All Aranet4 CO 2 monitors are calibrated before being shipped out. But please be aware, they should be recalibrated roughly once per year. This is possible through the app. To do so, go to the settings menu and select CO 2 calibration.De Aranet4 is zéér gebruiksvriendelijk en 'monkey-proof', omdat hij géén knoppen heeft en dus niet ontregeld kan worden door nieuwsgierige (kinder) vingertjes! 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.
