SAF Aranet4 Home: Wireless Indoor Air Quality Monitor for Office or School (CO2, Temperature, Humidity and More) Portable, Battery Powered, E-Ink Screen, App for Configuration & Data History

Product Information

Unlike the other carbon dioxide monitors, the SmartAir product uses an internal battery, which requires a charging port. It monitors the current CO2 concentration in the classroom and clearly signals with coloured lights when ventilation may be needed. If you’ve already done that, your item hasn’t arrived, or it’s not as described, you can report that to Etsy by opening a case. Over time, carbon dioxide sensors begin to drift, and if left unchecked, they will provide inaccurate readings over the weeks, months and years we use them. Etsy’s 100% renewable electricity commitment includes the electricity used by the data centres that host Etsy.

The American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE) notes anywhere below 1,000ppm as a generally acceptable level.Regarding +-50ppm+-5% being a large margin – the best sensors offer +-30ppm +-3% which is very much sufficient to determine the critical >1000ppm and >1500ppm thresholds. The Aranet4 Home simply displays the components of good air quality for your own wellbeing, your children, students, colleagues or people within your care.

You can set the screen to show a single reading (these can be scrolled between), and that’s all that is displayed on the screen. Within the app, you can enable the device’s alarm, choose how often it activates, set CO2 level thresholds, and more. So, the higher CO 2 in the room, the more you’re breathing air that someone else has already exhaled. Most purchases from business sellers are protected by the Consumer Contract Regulations 2013 which give you the right to cancel the purchase within 14 days after the day you receive the item. Using an NDIR sensor, the unit monitors the CO2 levels of each room and notifies you, via smartphone, when you need open a window to allow fresh air in.I appreciate the inclusion of this mounting hardware, as it makes any of these monitors perfect for office or classroom use. If you’re looking for something a bit less specialist-orientated, such as a monitor to identify poor ventilation, viral transmission chance, or the cognitive impact of carbon dioxide, then you’re in the right place. Since the product itself only has one button, this is where you will be changing all settings associated with the monitor. Either way, it is a significant limitation for the device, and it means that you can’t leave the device in your pocket or handbag and rely solely on the app while out and about. Recent studies have shown that CO2 concentration is a very good indicator for the presence of aerosols in the room.
