USB Type Portable Carbon Dioxide measuring device. Automatically measure the concentration of carbon dioxide in the air when plugged into a USB port. If the concentration is higher than 1600 ppm, it will be notified with a warning sound and light. A device that helps maintain pleasant indoor air quality.
You can check easily the CO2 concentration just by looking at the condition display.
- At 1601 ppm, the red LED lights up and preliminary warning sounds 5-6 times
- About 2000 ppm, the red LED blinks and sounds a warning signal beeps
- When the warning signal beeps, push the power button to turn off the sound
The main cause of sleepiness is carbon dioxide, it will let you know that the concentration of carbon dioxide increases. Make sure to ventilate to keep clean indoor air with easy measurement. It's very easy but really efficient.
~499ppm : Good / 500~899ppm : Normal / 900~1600ppm : Bad / 1601ppm~ : Very Bad
