enter the pairing state after the firsttime opening, and you can view the specific data on the APP after completing the connection. (Because it takes time to upload data, it is normal for the APP data to deviate from the real-time data of the detector.)【AQI Air Quality Level Indication Function】: Equipped with air quality level division function, use different color to show the different quality of the air being monitored, allowing you to more accurately and more visual know the current air conditions.【Strong Heat Dissipation】: Hundreds of ventilation holes reserved on the housing not only accelerate the convection between the air and the machine, thereby realizing effective detection, but also provide a fine heat dissipation effect.【Wide Applications】: Real-time detection, automatic refresh data, with multi-use. Suitable for agricultural planting, greenhouse vegetables, production warehouse, material processing, home interior, business offices, and etc.Specifications:Material: ABSColor: white, black (optional)Version: Wifi version, common version (optional)Battery: 1 * 2000mAh lithium battery (included)Display: TFT color displaySensor: semiconductor TVOC sensor, electrochemical CO sensor, infrared PM2.5 sensor, temperature and humidity sensorHCHO measurement ranges: 0-9.999mg/m³TVOC measurement ranges: 0-9.999mg/m³PM2.5/PM10 measurement ranges: 0-999μg/m³CO: 0-1000PPMCO2 measurement ranges: 0-5000PPMTemperature measurement ranges: 0-70℃Humidity measurement ranges: 0-99%RHAQI: 0-500Recharging method: USB Type-C interface, 5V 2AItem size: 70 * 90 * 35mm / 2.76 * 3.54 * 1.38inPackage size: 145 * 104 * 48mm / 5.71 * 4.09 * 1.89inPackage weight: 200g / 7.05ouncePacking List:1 * Air Quality Monitor1 * Type-C Cable1 * Guideline
