Digital CO2 WiFi monitor, temperature and humidity

Product detailed description

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

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

INTELLIGENT CONNECTION WITH WIFI APP
Connect the CO2 detector to the mobile phone APP via WiFi network. It is easy to receive and monitor detection data at any time. The datalogger can store data for one week. If the CO2 concentration exceeds the safety limit, it automatically sends an alarm to remind users to take appropriate measures.

LONG BATTERY LIFE
Designed with low energy consumption. After 30 seconds, the air quality monitor automatically turns off the screen to save energy. When you wave your hand, the screen lights up. It can be used for a long time without charging (working time approx. 23 hours).

MULTIFUNCTIONAL SCREEN
The CO2 monitor comes with a multifunctional screen that simply displays CO2 concentration, temperature and humidity, making it easier to understand and operate.

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

Calibration and settings 
1. Manual calibration:
Turn on the CO2 detector and place it in an environment with a CO2 concentration of about 400 ppm (outdoors
or by 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:
24 hours after switching on, the sensor will set itself to the lowest CO2 value, so make sure that within 24 hours you allow some ventilation time to ensure the accuracy of automatic calibration.

3. Automatic brightness adjustment:
The carbon dioxide detector can automatically adjust the screen brightness according to the ambient brightness and automatically turns off the screen to reduce energy consumption after 30 seconds without movement (can be set in the APP), at the same time, you can still check real-time data in the APP.

4. Note
The air quality metre is supplied with a battery, which must be charged for 5 minutes and calibrated before first use.

For best results, place the CO2 detector above the CO2 entry point and below 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 accuracy depends on the sensor type. The most accurate CO2 sensors are those that use Non-Dispersive Infrared (NDIR) measurement technology, because this technology provides the greatest measurement accuracy and stability.
NDIR sensors use special filters that allow only light of a certain wavelength to pass through. Gases such as CO2 absorb light in certain wavelength ranges, which allows 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.
