Operating Instructions
This product has the function of CO2 concentration detection and alarm, as well as the function of
temperature and humidity detection and display.
LED panel displays information such as CO2 concentration, ambient temperature and humidity
Power supply and startup
4.1
At the same time, the product is equipped with external AC power adapter for power supply and
built-in backup rechargeable polymer lithium battery, which can work for 12 hours after AC power is
cut off, and remind users to charge when the battery is low voltage
The product is started when the AC power adapter is inserted or the backup power is switched
on. It takes 3 minutes to warm up after the product is started. When AC is powered, the traffic light
indicator window is always on, while when backup battery is powered, the traffic light indicator
window flashes. When the backup battery is low voltage. The traffic light indicates that every 4S will
be bright yellow.

Product Overview
GS241T-H02 compound carbon dioxide temperature and humidity alarm, adopt high-precision NDIR
carbon dioxide sensor, digital temperature and humidity sensor chip, is used for detection of the indoor
environment of the carbon dioxide content, temperature and humidity and display in the screen, when they
tested the carbon dioxide, temperature or humidity is beyond the preset alarm value, the product will be in
the form of traffic lights remind users. Avoid excessive CO2 concentration to cause harm to human body,
protect the safety of life and property.
This product is suitable for CO2 concentration, temperature and humidity monitoring in ordinary houses,
offices, schools and other places. It is built with a 24-hour automatic calibration algorithm program, do not
need manual calibration.
2 Product Features
4.2 CO2 detection and display
This product can detect and display the CO2 concentration of the surrounding environment and
give corresponding warning. The default warning value is 800ppm, and the default alarm value is
1500ppm. If users have more reasonable suggestions please discuss with us.
Good condition: When 800ppm, the warning window shows green color (See figure 3);
