In the second image, I decided to take the Aranet4 Home into a shopping mall. The large shopping mall appeared well-ventilated, as readings never exceeded 800 ppm. Again, this excellent result shows that a well-ventilated shopping mall can manage carbon dioxide levels!
The advantage of this type of display is its low power requirements and its high contrast is easily read if there’s good ambient lighting. The unit can sit on table or shelf, or be wall mounted if you prefer. Sensors
Aranet4 HOME is an innovative battery-powered stand-alone bluetooth sensor.
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. This sensor has a CO2 ppm accuracy of ±30 ppm or ±3% of reading. This is the same accuracy as mentioned on Aranet’s spec sheet. This puts it among the market’s most accurate carbon dioxide monitors, as this is the best accuracy specification seen on a consumer-grade monitor. While there are other monitors with a stated accuracy of ±30 ppm or ±3% of reading, nothing I’ve come across is more accurate. 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:
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! 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. 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.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! If you are an individual user looking for a carbon dioxide monitor, the Aranet4 Home is the device for you. If you need to monitor multiple devices – such as in a school where you might have a monitor in every classroom, the Aranet4 PRO is more capable. There’s no VOC or PM2.5 detectors here, but the on-board electronics use a special type of ‘NDIR’ sensor for CO₂ measurements…
