PV28-AW Smart WIFI Mini CO2 Detector, Portable 3-in-1 Indoor Air Quality Monitor, Digital CO2 Temperature Humidity Meter Monitor Carbon Dioxide Detector Measuring Range 400-5000 PPM CO2 Tester

OverviewFeatures: Mini 3-In-1 CO2 Detector: 3 in 1 CO2 detectors have a simple, small and portable design, which can detect carbon dioxide concentration, temperature, humidity. CO2 detection range is featured from 400 to 5000PPM, temperature detection range from 0 to 50℃ and 0-99%RH for humidity detection range, fits well for agricultural planting, production warehouse, raw material processing, home, school, office, and other occasions. LED Screen Display: Full-color display and large screen design ensures its super easy readings with LED digital display for eye protection. it can clearly display the current value of CO2, temperature and humidity. CO2 Concentration Stage & Alarm: This CO2 detector is functional with 5 stages of CO2 concentration—good stage (400-799 ppm), moderate stage (800-1199 ppm), poor stage (1200-1599 ppm), unhealthy stage (1600-1999 ppm), and very unhealthy stage (2000-5000 ppm). When the CO2 concentration value reaches or exceeds 1500PPM, the product will sound an alarm. Automatic Brightness Adjustment: According to the brightness of the surrounding environment, the screen brightness will be adjusted automatically to make the screen visible and not dazzling. Distance Sensing Wake-up (On/Off in APP): This product contains a distance sensor, in the dormant state(dormancy after 30 seconds without sensing, you can close this function in the APP) you can approach the product directly or wave it in front of the product to wake up the screen. WIFI Connection: Built-in WIFI, you can query data at any time in the mobile APP. Remind the family to purify the air. The sensor can still transmit data to the cloud through WIFI when the screen is off. View real-time values through APP. Power Supply: CO2 detector has a built-in 1200mAh large capacity rechargeable lithium battery. It can be charged via USB type-C data cable.
