Smart air quality monitor with carbon dioxide detection: the Laser Egg+ CO2

Have you ever felt tired after a meeting at the office? Is your child often tired in the classroom? Do you sometimes wake up in the morning and not feel fresh and rested? All this can be related to a poor oxygen supply. 

The Kaiterra Laser Egg+ CO2 provides a great solution for you. It not only measures harmful PM2.5 but also tracks CO2 levels in your air. Say goodbye to afternoon drowsiness and hello to fresh air! Get a clearer mind with the Kaiterra Laser Egg+ CO2. 

The Kaiterra Laser Egg+ CO2 is empowered with highly accurate sensors that both individually count fine dust particles and keep track of your oxygen quality. Furthermore, it measures temperature, humidity and provides weather forecasts.

Thanks to its 2.4 GHz Wi-Fi connectivity, the Kaiterra Laser Egg+ CO2 connects with other home appliances via Apple HomeKit and IFTTT. Use the Kaiterra App to monitor pollutants and CO2 at home from anywhere to keep your air under full control.

  • No more pollution related allergies
  • Better lung health
  • Healthy skin
  • Improved sleep quality
  • Increased productivity


The Laser Egg+ CO2 is powered by an array of highly accurate sensors and Kaiterra’s innovative cloud-based calibration and equipped with a non-dispersieve infrared (NDIR) sensor to calculate the CO2 concentration in the air.

• Air Pollution Tracking: the Laser Egg+ CO2 uses laser-based scattering technology to quickly detect fine particulate matter that are 2.5 microns or less in diameter (PM2.5) to help protect your family against these harmful air pollutants. Also useful as a guide to understand efficacy of air purifiers, and track life of HEPA filters.

• Monitors Carbon Dioxide: the Laser Egg+ CO2 tracks carbon dioxide, an inexpensive and powerful way to monitor the risk of people getting COVID-19. In indoor environments excess carbon dioxide levels increase the risk of transmission. An excess of CO2 also makes you feel fatigued and sluggish, which is not great for productivity. Reduce indoor build-up of carbon dioxide that affect your health and comfort.

• Temperature & Humidity: manage your indoor air quality for maximum comfort. Get real time updates on temperature, humidity and weather forecasts to plan your day.

• Mobile: at home or on the go, monitor from anywhere with the Kaiterra app. Get access to historical trends and receive alerts when the air exceeds predetermined thresholds. And make smarter decisions for your home that last.

• Connected: works with other home appliances via Apple Home and IFTTT. Set up your smart home ecosystem to automatically protect your home against pollutants and allergens.

• WIFI-enabled: (2.4 GHz connection) support for iOS and Android smartphones and tablets.

How to calibrate the CO2 sensor in your Laser Egg+ CO2

The Laser Egg+ CO2 can be automatically calibrated over time, and can also be calibrated manually as needed.

Automatic Calibration
All sensors drift over time, but thanks to the built-in self-correcting ABC-algorithm (Automatic Baseline Correction), the calibration process is automated.

The ABC-algorithm constantly keeps track of the sensor’s lowest reading over time and slowly corrects for any long-term drift. In a normal indoor environment, the CO2 level drops to nearly outside air at some point during a week. The sensor will sample the CO2 values for a week and compare the lowest reading to the background level value reading, and adjust the baseline accordingly.

Manual Calibration
Because of the nature of NDIR sensors, there may be a reduction in accuracy because of rough handling, transportation, and aging. The ABC-function can tune the readings back to the correct level for an extended period of time. However, you can also choose to calibrate your device manually for a faster result if you notice a significant drift.

Follow the steps below to manually calibrate your Laser Egg+ CO2:

  1. Put your Laser Egg+ CO2 by a window, making sure it’s exposed to fresh outdoor air, and keep it connected to your Wi-Fi at the same time.
  2. Leave the device running until the CO2 concentration reading has stabilized, within a +/- 6% window. Make sure not to exhale near the device during this process.
  3. Open your Kaiterra Live Air app, and enter the device setting page. Initiate the manual calibration process by pressing the “Calibration” button.
  4. The CO2 concentration should read stably below 450ppm and your manual calibration is done. If not, please perform the process again.
