The Temtop LKC-1000S+ (and the similar, less fully featured LKC-1000S and LKC-1000E) are handheld monitors. This is not to be confused with home weather stations, which usually don’t measure AQI. It’s possible to program a connected monitor to turn on a smart air purifier or central AC in the event of poor air quality. For example, if the concentration of CO2 exceeds the normal limits this may result in fatigue, decreased concentration, headaches, and other health conditions. For example inside your bedroom, where the windows and the doors are often closed, the carbon dioxide level can rise very quickly. The only thing you need to do is to connect it to the power grid with the AC adapter included in the package. We did this three times, clearing the air between tests with a Blueair Blue Pure 211+ air purifier. For people not familiar with the CO2 scale, small happy face icons will blink on the screen if the current levels of VOCs are normal. This consistency gave us confidence in the M10’s accuracy as well. While both can be used to measure indoor air quality (IAQ), these sensors are not interchangeable. The Awair Glow is a smart plug that gives a measure of indoor air quality based on VOC, temperature, and humidity readings, but it does not measure particulates, a requirement for inclusion in our testing. To keep the values coming out reasonable, you'll need to calibrate the sensor. This is a comparison table of some of the best air quality meters on the market. The SGP40 is Sensirion’s digital volatile organic compounds (VOC) sensor designed for easy integration into air treatment devices and air quality monitors. When he’s not here, he’s on his bike.
