WiFi CO2 Detector, Air Quality Monitor, Temperature and Humidity Tester, Thermometer Hygrometer for Home

1.Indoor CO2 Monitor: Compact design with a hollow back, easy to carry.Bright and attractive LEDs provide easy reading.Real-time monitoring of CO2 levels.This air quality monitor is ideal for indoor use, such as in living rooms, children's bedrooms, classrooms, offices, and enclosed spaces.2.Tuya App: Connected to 2.4 GHz Wi-Fi (hub not included), the device allows you to remotely monitor CO2 levels via the Tuya app, send short- and long-term monitoring results directly to your smartphone via Wi-Fi, and easily view CO2 reports.3. Air quality monitoring: A low CO2 level is safe for the human body, but above a certain threshold, it affects respiration and that of other organisms.It is therefore essential to monitor the CO2 content of the air to protect your health.4.High-end NDIR detection: This mini CO2 meter features a high-precision NDIR sensor, capable of quickly and accurately detecting carbon dioxide levels.When the CO2 level in the air exceeds the set alarm value of 1,000 ppm, an audible signal will sound to remind you to open a window or activate the air purifier to maintain air balance.If the alarm is not suitable, press the power button once to turn it off.5.Easy to use: The CO2 detector calibrates itself automatically each time it is switched on.Please place it in a well-ventilated area and calibrate it for 1 to 2 minutes before using it normally.SpecificationsItem Type: CO2 DetectorCarbon Dioxide Detection: NDIRSmart App Control: Wi-Fi app for TUYA, data transfer to mobile phones, compatible with Android and iOS phones, and available in multiple languages.
