Features:
14 in 1: Multifunctional air quality detector real-time monitors the CO2 concentration, CO concentration, TVOC value, HCHO value, PM2.5/PM1.0/PM10 value, temperature and humidity in the air, with time and date display, and can also be used as an alarm clock, timer or stopwatch.
APP Control: Support connecting Tuya APP to monitor data in real time, so you can easily view it no matter where you are, and also view historical data. Every time you connect APP, the time and date will be automatically updated with your phone, no need to set, more convenient and smarter.
Clear Display with Alarm Function: 2.8" color digital display, clear and easy to read, Celsius/Fahrenheit can be switched, with multiple display modes, you can set it according to your needs. Support alarm function, parameter abnormal will sound an alarm to remind you to make adjustments in time.
Built-in Battery & Quick Heat Dissipation: Equipped with 2000mAh high-capacity battery, low power consumption and long endurance, free from the bondage of wires, the placement can be adjusted at will. With multiple ventilation holes, accelerating the convection between the air and the detector, to achieve the purpose of effective detection and quick heat dissipation at the same time.
