Review: Ultra fiable y muy cómodo. La batería dura muchísimo. La apliación para móvil es fantástica. 100% recomendable.
Review: Der CO2 Sensor ist gut und sicher verpackt. Macht einen wertigen Eindruck und sieht gut aus. Dank der Verwendung normaler Batterien und seiner geringen Größe kann man ihn einfach mal in ein anderes Zimmer stellen oder mitnehmen. Viele andere vergleichbare Geräte haben einen kurzzeitigen Akkubetrieb oder erfordern einen Netzanschluss. Die Bluetooth-Verbindung mit der zugehörigen App ging schnell und einfach. Die Verbindung ist stabil. Kein Re-Connect erforderlich wenn man zB außer Reichweite war. Die Anzeige am Gerät ist gut ablesbar. Meist schaue ich aber über die App, da hier auch der zeitliche Verlauf angezeigt wird. In der c‘t 27/2023 war ein Bericht über CO2 Messgeräte und der Aranet4 hat mich trotz des hohen Preises mein Interesse gefunden. Das hat sich im Betrieb bestätigt. Mit dem Gerät und der App bin ich sehr zufrieden. Was negativ zu erwähnen ist, ist die starke Preiserhöhung um €30 wohl zum Februar 2024. Ende Januar hab ich noch €179 bezahlt, aktuell kostet er €209. Versand kommt schnell aus Lettland (EU) mit €10 VK.

## Questions & Answers

**Q: Why do I need monitor CO2 concentration?**
A: High CO2 levels can negatively affect your well-being, comfort, and productivity. For example, if CO2 levels reach 1000 ppm, your cognitive abilities drop by 15%. At 1400 ppm and above, they decrease by a staggering 50%.

**Q: What is the NDIR sensor and why is it preferred over other types of sensors?**
A: Because it provides a higher precision than regular electrochemical sensors because CO2 is uniquely detectable with no interference from other gasses. Besides that the lifespan of the NDIR sensor is much longer and less recalibration is needed.

**Q: Why is Aranet4 considered the gold standard in CO2 monitoring?**
A: Aranet4 excels with multi-sensor accuracy, real-time alerts, app connectivity, and user-friendly design, highly praised by numerous satisfied customers.

### ⭐⭐⭐⭐ Review
*by J***I on 25 May 2024*

Living in a closed space with generally poor ventilation in an apartment, is the reason why I purchase this product. However , after been using it for over 2 weeks now, I have come into conclusion that most of us may not even need it because the CO2 in a closed space in my apartment rarely goes above 800ppm throughout the day. The only situation where it can go above 800ppm is when gas stove is used. However, carbon dioxide monitor or reader can be useful if you live in a rather tight space whereby there are three or more occupants as CO2 is mainly produced by respiration or breathing other than from burning gas. As you can see in the picture here, the screen on the aranet 4 is quite a bit sharper and contrasty than the inkbird and the design is more attractive due to semi transparent plastic case and the underlying board design is partially visible whereas inkbird has a bit of off-white coloration. The measurement is very similar to one another due to similar NDIR sensor used. As mentioned, the main deciding factor whether you need this or not is how many occupants in a space or how crowded the space is. More people occupying same space at same time, the higher the CO2 produced. For the app, I like how you can just drag along the chart to see the reading. However, aranet app only allows 7 days of data to be kept on the device before it gets overwritten where as the inkbird can keep data on the device for up to 30 days. Basically, aranet app is more polished , however, data storage is only limited to 7 days when set to 5 minutes measurement interval instead of 30 days (on device) to 1 year on inkbird (only when is synced to the phone). Addendum : Aranet has released a firmware in Dec 2023 that allows you set how long the data can be stored on the device and this depends the measurement interval, i.e. 2 minutes interval equivalent to 7 days of storage; 5 minutes for 15 days ; and 10 minutes for 30 days of storage . Besides CO2 readings, you will also get ambient temperature, humidity and atmospheric pressure readings. However, this device is not equipped with complete suite of air quality sensors, what is missing out here are quite substantial and these include volatile organic gas (VOC) , radon, particulate matters , carbon monoxide which are important parameters to determine the air that you breath is safe. And of course to have all these sensors included in an air quality monitor will costs a fortune for regular consumer. The Bluetooth range on the Aranet 4 is slightly shorter than inkbird from the distance I tested. 7-8 meters on inkbird vs 6 metres on aranet4. aranet 4 has a hidden feature of boosting it's Bluetooth range at presumably small cost of battery life by a toggle under Bluetooth setting of the app to about the same range as inkbird. One important thing when placing the double AA battery in, is quite different from other device, make sure you place the positive side first then only negative due to there is a plastic lip at the positive side. Battery is super long lasting due to energy efficient E ink display and low energy Bluetooth and especially interval measurement is set to 5 or 10 minutes. Downside to this is that you can only get Bluetooth connection to sync the data to phone rather than wifi and can't assess the data if not in the Bluetooth range or if away from home. Aranet claims there is a smart home integration app called homey but I guess it can be complicated to setup due to the integration is not mainstream like homekit or google home.
