Description: This high-quality product needs to be used with a ZigBee 3.0 gateway. The smart air box is a smart device for remote monitoring of home air environment. It can also detect 5 environmental parameters such as formaldehyde, VOC toxic gases, CO2, temperature, and humidity. When the environmental parameters exceed the standard Time-automatic Tuya smart home air conditioners, fresh air fans, humidifiers, and air purifiers optimize the home environment. Intelligent air box detection range: formaldehyde, VOC gas, CO2, temperature, humidity detection range: formaldehyde: 0-10.0 (mg/m3) VOC: 0-99.9 (ppm) carbon dioxide: 0-1000 (ppm) temperature: 0-60 () Humidity: 0-95 (%) After pairing with the APP, it can be linked to various smart home products. For example, when formaldehyde/VOC exceeds the standard, the smart air purifier automatically turns on; when carbon dioxide exceeds the standard, the smart fresh air fan automatically turns on; when the temperature is abnormal, the air conditioner temperature is automatically adjusted; when the humidity is too low or too high, smart humidification The device will automatically turn on/off; when it detects that a certain parameter exceeds the standard, an information alarm will be sent (the above smart linkage functions need to be matched with smart home products) Specifications: Working temperature: -20-- 85 Working voltage (rated): 4.8- 12V Working current: 10-496ma Size: 90*90*35mm Power supply method: USB 5V/1A Communication protocol: ZigBee3.0 Color: White Shell material: PVC Packing list: Smart aviation box X1 Instructions for use X1 Card pin X1 USB power cord X1Note: Please do not place the air box in areas with excessive oil fumes, strong convection air or high concentrations of organic gases for a long time, otherwise the sensor will be damaged.
