CO2 Detector,WiFi Air Quality Monitor,Portable CO2 Monitor,Omlcines Accurate NDIR Sensor Carbon Dioxide Detector with Alarm,CO2 Temperature and Humidity Meter with Data Logger for Home Indoor Outdoor

Description Product Features: 1.Manual Calibration Turn on the CO2 detector and place it in an environment with a CO2 concentration of about 400PPM outside or by a window for convection ventilation)for 5~10 minutes, press the multifunction button 3 times in quick succession.

After a few seconds, the device will automatically shut down, manual calibration will be completed, and finally the device can be restarted for normal use.

2.Automatic Calibration After 24 hours of power on, the sensor will set the lowest CO2 value to zero for 24 hours, so please make sure there is some ventilation time during the 24 hours to ensure the accuracy of the automatic calibration.

3.Automatic Brightness Adjustment The carbon dioxide detector can automatically adjust the screen display brightness according to the surrounding brightness and can auto rest the screen to reduce energy consumption after 30s of no interference (it can be set in the APP), at the same time, you can still check the real-time data on the APP.

4.Cautions The air quality meter comes with battery please charge it for 5 minutes before using it for the first time and calibrate it before use avoid running out of battery due to long period of non-use or other reasons.
