SwitchBotMeter Pro CO2 Indoor Air Quality Monitor 5-in-1, CO2 Alarm, Large Display, Bluetooth Air Quality Tester for Home, Office, 2-Year Data Storage

The SwitchBot Meter Pro CO2 Indoor Air Quality Monitor is an excellent tool for maintaining a healthy environment. Its 5-in-1 functionality provides real-time CO2 readings alongside temperature, humidity, and more, making it versatile for home or office use. The large display is easy to read, and the Bluetooth connectivity ensures seamless data tracking with 2-year data storage to monitor trends over time. This will save my home from potentially health issues.I paired it with the SwitchBot 4-in-1 Air Purifier, and they work perfectly together. The purifier’s H13 HEPA filter and aromatherapy feature not only improve air quality but also create a pleasant atmosphere. Its RGB lighting adds a stylish touch, and the combination ensures I can monitor and purify the air simultaneously. This duo is a fantastic investment for anyone prioritizing health and comfort.

It works perfectly, I like the big screen, the measurements are accurate. I started monitoring the co2 level, and reminded me to open the window to have fresh airs

For my purposes I need relatively frequent readings, and this meter is not optimal for this need. I decided to keep it anyway as it does work well . Customer support was excellent and they offered to refund me without even returning the item.

$69 with a 30% off coupon is a great price! They used the industry's best NIDR sensor for CO2 readings. I don’t have a Hub, but the setup is simple. I added it to Home Assistant via Bluetooth, and it works perfectly.I am comparing it to the Aranet4 for accuracy, and the readings are similar, with less than a 50 ppm difference between them. I have included a comparison graph for your reference; the yellow line represents the Switch Bot, while the blue line represents the Aranet4.The only downside is that when running on battery, the CO2 reading is recorded every 30 minutes, but when plugged in with a USB-C power cable, the readings occur much more frequently.Overall, I am happy with my purchase and plan to buy more units for each bedroom.

I wanted another CO monitor, but this is a CO2 monitor. Be careful. As I was trying it out, saw the CO2 level going up, my wife was frying something, and forgot to turn on the vent. Levels were red. I open the vents, and windows, and levels came back down to acceptable range. So now I will keep it on the kitchen counter for my wife.

I have an "home office" (a bedroom used as an office).Baseline CO2 outdoor is about 410 ppm. Usually showing 430-440 at home, that's well-enough calibrated for me.When I work for a few hours in that room with the door closed, the concentration goes past 1000 ppm pretty fast.Open the door or crack a window: goes down.Too high CO2 just makes you less effective. It's not dangerous at these levels, but if you go over 1500 or 2000, your ability to concentrate will be reduced.I will get another one when on sale to add to one bedroom that is rather small to measure the CO2 concentration over night to see if there's enough ventilation.Basically CO2 levels = a way to measure air quality.

Very slow polling rate.USB position and cutout size makes finding a compatible USB C cable challenging.

Easy to setup and works
