The Qingping Air Monitor Lite also supports Apple Homekit, so if you’re an Apple user, you’ll be able to integrate this little air quality monitor into your smart home. Outdoor concentrations vary between approximately 400 ppm (parts per million) in clean air areas and 500 ppm in urban areas. Duomo offer the widest solutions for air quality monitoring, offering NDIR elements, fully connected sensors, CO2 monitors and transmitters, standalone solutions and safety.

As you can see on the graph, all monitors recorded within 30 ppm of each other between 900 and 1150 ppm.For example, while the Vitalight Mini CO2 Detector is very accurate, it has a short battery life and a frustrating automatic calibration feature. At the end of the day, whether you’re seeing 1400ppm or 1500ppm, both indicate that better ventilation is needed. This is because this article is aimed entirely at users looking to pick up a consumer-level monitor. This means that you cannot view data on the app when you’re out and about (and not connected to WiFi).

To reduce the risk of fire, never leave vintage electrical or electronic products plugged in unattended. I chose not to include monitors I haven’t experienced because I believe it’s disingenuous to recommend something I haven’t tried. Perfect for individual use in the home or for larger facilities such as businesses, schools, factories and offices, they are extremely easy to install, use and maintain.The nail file was perfectly described, however only gave 4 stars as the listing says 'in aluminium case' and mine is in an 'eco storage case' (i. What is most interesting to me in this graph is the larger variation between the measurements taken by the two Aranet4 Homes than between the SmartAir Monitor and either Aranet. This means that increasing the air exchange rate can reduce the aerosol concentration and therefore the risk of infection. CO2 measurement accuracy is provided for a range 0 … 5000 ppm, temperature 15 … 35 °C (59 … 95 °F) and relative humidity 0 … 80 %.

Thankfully, the thresholds for each colour can be adjusted in the app, meaning you can set each colour to your desired levels. The app also allows you to view data for up to one year, and you can quickly export data as a text file if you want to dive deeper into the results. You are correct to assume that pressure has a role in the CO2 measurement process – the CO2 reading is heavily affected by the atmospheric pressure (an overview available here https://www. On the other hand, if you want a portable monitor to take everywhere, you’ll want to look for the longest battery life possible. On the flip side, the SmartAir CO2 Monitor relies on an internal battery with a 6-30 day battery life (depending on your CO2 measurement and uploading intervals).I hate having so many devices to charge, and the Vitalight Mini CO2 detector is yet another device requiring daily charging. The PRO model costs more than the Aranet4 Home, and the Base Station costs many hundreds of dollars on top of that. For example, in Aranet’s ecosystem, you would need Aranet4 PROs (not Aranet4 Homes) with an Aranet Base Station for this functionality.
