Indoor Quality Meter 8 In 1 CO2 Detector NDIR Sensor Detect PM2.5 PM10 PM1.0 HCHO TVOC Temp Humidity with Alarm

ACCURATE SENSING: Standalone CO2 NDIR sensor offer higher accuracy and greater interference resistant than semiconductor sensor. The concentration of carbon dioxide in the can be accurately measured WITH ALARM: PM2.5 of indoor quality meter warn by color. Green 0‑50, yellow 51‑100, orange 101‑150, red greater than 151. The bigger the data, the worse the pollution. When PM2.5 is greater than 100, an audible alarm will be triggered. If both CO2 and PM2.5 exceed the standard, CO2 will give priority to the alarm

ENDURANCE: quality meter built in 2000mAh re able lithium battery, use the USB charging cable in the package, input 5V voltage, 3‑4 hours can be d, d after 7‑8 hours of sustainable work Item Type: Indoor Quality Meter Material: ABS Use: 8 in 1 indoor quality meter with 5 professional sensors to accurately detect CO2, PM2.5, HCHO, PM1.0, TVOC, PM10, temperature, and humidity Battery: 1 x lithium battery(2000mAh)
