ELCTRONIC CO2, TEMP, HUMIDITY MONITOR. WI-FI

REAL-TIME MONITORING: Equipped with professional NDIR sensors, this smart air quality monitor can monitor CO2 concentration, temperature and humidity inside or outside in real time.
SMART WIFI APP CONNECTION: Connect the CO2 detector to your cell phone app via wifi, it is easy to receive and view detection data at any time, the data logger can save data for a week. And if the CO2 concentration exceeds the safety limit, it will automatically send an alarm to remind users to take appropriate action.

LONG BATTERY LIFE: Designed with low power consumption, 30 seconds without interference, the air quality tester will automatically turn off the screen to save power, when you wave your hand, it will wake up the screen. It can be used for a long time without recharging (working for about 23 hours).

MULTIFUNCTIONAL SCREEN: The CO2 monitor is equipped with a multifunctional screen that displays CO2 concentration, temperature and humidity in a simple way, making it easy to understand and manage.

LIGHT AND PORTABLE: Compact and lightweight design, the CO2 meter is easy to hold and suitable for various occasions such as home, school, office, car and growing room, etc. Essential for a healthy lifestyle.

1. manual calibration

Turn on the CO2 detector and place it in an environment with a CO2 concentration of about 400PPM (outside

or through a window) for 5 - 10 minutes, press the multifunction button 3 times in 3 short intervals. After a few seconds, the device will automatically turn off and the manual calibration will be completed.

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, so make sure there is some ventilation time within 24 hours to ensure the accuracy of the automatic calibration.

3 Automatic brightness adjustment

The carbon dioxide detector can automatically adjust the screen brightness according to the brightness of the environment, and will automatically turn off the screen to reduce power consumption after 30 seconds of no movement (this can be set in the app), at the same time, you can still check the real-time data in the app.

4 Note

The air quality meter comes with a battery, which should be charged for 5 minutes before first use and calibrated .

---

For best results, place the CO2 detector above the CO2 inlet point and below the ventilation inlets/outlets, approximately at the level of the tops of the plants.

There are several types of CO2 sensors that can be used in CO2 monitors, and the accuracy depends on the type of sensor. The most accurate CO2 sensors are those that use Non-Dispersive Infrared (NDIR) measurement technology, as this technology provides the greatest accuracy and measurement stability.

NDIR sensors use special filters that allow only light of a certain wavelength to pass through. Gases, such as CO2, absorb light in specific wavelength ranges, which allows for accurate measurement of CO2 concentration. NDIR sensors are used in professional CO2 monitors and are considered the most accurate.

Electrochemical or capacitive sensors are also used in CO2 monitors, but their accuracy is usually less than that of NDIR sensors.
