METER / SENSOR OF CO2 CONCENTRATION OF CARBON DIOXIDE TEMPERATURE HUMIDITY WITH WIFI SMART HOME COMMUNICATION - TUYA APPLICATION LATEST MODEL WITH BUILT-IN WIFI MODULE AND BLUETOOTH MODULE (FOR EASY PAIRING) CALIBRATION FUNCTION Automation related to CO2 levels, alarm setting and much more! The most important functions of the smart CO2V1 sensor: High-quality infrared CO2 sensor (NDIR) Built-in 2.4Ghz WIFI module Operation and automation via the TUYA app! Additionally, a built-in thermometer and hygrometer Power supply via microUSB 5V port (USB cable included - no power adapter) Measurement range of CO2 concentration 400-5000 µg / m³ [PPM] Temperature measurement range: -10 50 [ C] Humidity measurement range: 0 100% RH Sound signaling after exceeding the safe concentration Air quality signaling via colored charging bar: Good (green) / Normal (yellow) / Medium (orange) / Bad (red) Audible alarm function when the set CO2 value is exceeded Audible alarm disable function! NOVELTY CO2 sensor calibration function! NOVELTY OPERATION THROUGH THE ADVANCED TUYA APP - FOR PHONES WITH ANDROID AND IOS COMPLETE MEASUREMENT HISTORY AUTOMATIC ACTION FUNCTION THE POSSIBILITY OF REMOTE VIEWING PARAMETERS FROM ANY PLACE IN THE WORLD The effect of CO2 concentration on the human body: 350-400 ppm: concentration in the external environment 350-1000 ppm: clean air and light breath (WHO upper threshold in areas of permanent human habitation) 1000-2000 ppm: the air feels stale and stuffy, feeling drowsy 2000-5000 ppm: in debilitated people with respiratory diseases, coughing occurs, and sometimes there are fainting or fainting, headaches, drowsiness, increased heart rate, slight nausea and inability to concentrate From 5000 ppm: severe hypoxia RANGES OF CO2 INDICATION THROUGH THE METER 400-1500ppm GREEN LED STRIP - GOOD AIR QUALITY 1501-3500ppm LED YELLOW STRIP - NORMAL AIR QUALITY 3501-5000ppm LED STRIP ORANGE - MEDIUM AIR QUALITY up to 5000ppm RED LED BAR - POOR AIR QUALITY AUDIBLE ALARM The device has a built-in audible alarm. Each time the carbon dioxide reading is above the set threshold and the next reading is higher than the previous one - the meter will beep to inform about the increase. We also have the option to completely disable the audible alarm.
