Tuya Wifi Portable Air Quality Meter 8in1 PM1.0 PM2.5 PM10 CO2 TVOC HCHO Temperature and Humidity Tester LCD Color Screen Carbon Dioxide Detector with Time and Date Display Function

Features:
【8in1 Air Quality Tester】: This detector can be used to test and display the concentration of PM1.0, PM2.5, PM10, CO2, TVOC, HCHO, temperature and humidity at the same time. And also has WiFi function.
【High Accurate Sensors】: Uses high-precise NDIR infrared carbon dioxide sensor, laser particle sensor, semiconductor sensor, optical sensor and distance sensor, with high sensitivity, superior interference resistance ability, stable working performance, with low power consumption.
【LCD Color Display】: This air quality monitor with a large LCD color display, it can automatically adjust the display brightness according to the surrounding brightness, so that the data is clearly visible and the screen is not harsh. ​Support switching the display content between HCHO TVOC and PM1.0 PM10 at power on.​
【Sleep Approach Wake-up】: The screen can be automatically turned off to reduce energy consumption after no operation, and the sensor can still transmit data to the cloud through WIFI when the screen is off, and you can view the real-time values through the APP. This product contains a distance sensor, in the dormant state (dormancy after 30 seconds without sensing, you can close this function in the APP) you can approach the product directly or beckon it in front of the product to wake up the screen.
【Easy Calibration】: Two calibration methods design, turn on the device and place it for 5~10 minutes, then press multi-function button three times for manual calibration and it will automatic calibration after 24 hours of power on.
【Cellphone Tuya APP Control】: Search for Tuya APP in the application program, the device will 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.)
【Parameters Setting】: Support to set the PM2.5 CO2 alarm value, alarm sound, temperature unit switching, screen off function switching and screen off time setting in the settings page.
【AQI Air Quality Level Indication Function】: It will change the signal color according to the air quality index, and allowing you to more accurately and more graphic 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.
