INKBIRD Smart Air Quality Monitor Ndir CO2 Monitor Bluetooth with App | 3 in 1 Battery Powered Indoor CO2 Detector for Carbon Dioxide & Temperature & Humidity for Home, Office, Grow Tent (IAM-T2)
Bluetooth CO2 monitor with a 0–9999 ppm range, ±40 ppm ±5% accuracy and a backlit LCD that also shows temperature and humidity. A built-in 3000 mAh lithium battery charges over USB-C, and it logs 30 days of data with a buzzer and colored indicator lights for alarms. Accuracy is looser than the ±(30 ppm + 3%) models, but it is much cheaper than those and heavier than the smallest units at 0.41 lbs (0.19 kg).
