Tuya Wifi Smart Air Box Quality Monitor CO2 Sensor Temperature and Humidity VOC Formaldehyde Gas Detector Automated Alarm Description: 1. The smart air box is a home for smart devices that remotely monitor the air environment. It can also detect formaldehyde, VOC toxic gases, CO2, Tuya smart home air conditioners, fresh air fans, humidifiers, air purifiers and other five environmental parameters such as temperature and humidity will automatically optimize the home environment when the environmental parameters exceed the standard. 2. After pairing, it can be linked with various smart home products through the APP. 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 air box 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) 3.
