Digital CO2 WiFi monitor, temperature and humidity

Digital CO2 WiFi monitor that measures CO2, temperature and humidity in real time.

Real-time measurement
Equipped with professional NDIR sensors, this intelligent air quality monitor can monitor indoor or outdoor CO2 concentration, indoor or outdoor temperature and humidity in real time.

SMART CONNECTION WITH WIFI APP
Connect the CO2 detector to your mobile phone APP via WiFi network. It is easy to receive and monitor detection data at any time. The data logger can store data for one week. 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 in mind. After 30 seconds, the air quality monitor automatically turns off the screen to save power. When you wave your hand, the screen lights up. Can be used for a long time without charging (working for about 23 hours).

MULTIFUNCTION SCREEN
The CO2 monitor comes with a multi-function screen that displays CO2 concentration, temperature and humidity in a simple way, making it easy to understand and operate.

LIGHTWEIGHT AND PORTABLE
Compact and lightweight design. CO2 monitor is easy to hold and suitable for various occasions such as home, school, office, car, grow room, etc.

Calibration and setup
1. Manual calibration :
Turn on the CO2 detector and place it in an environment with a CO2 concentration of about 400 ppm (outdoor
or window) for 5 - 10 minutes, press the multi-function button 3 times at 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:
24 hours after power-up, the sensor will set to the lowest CO2 value, so be sure to allow 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 automatically turn off the screen to reduce power consumption after 30 seconds of no movement (can be set in APP), at the same time, you can still check the data in real time in APP.

4. Note
The air quality meter comes with a battery that needs to be charged for 5 minutes and calibrated before first use.

For best results, place the CO2 detector above the CO2 inlet point and below the ventilation inlets/outlets, approximately at the level of the plant tops.
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 stability of measurement.
NDIR sensors use special filters that only pass light of a certain wavelength. Gases such as CO2 absorb light in certain wavelength ranges, allowing 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 lower than that of NDIR sensors.
