Hismart TUYA Air Quality Monitor

TUYA Smart Wireless Air Quality Monitor with Temperature & Humidity Sensors, CO2, PM2.5 (Fine Particulate Matter), PM10 (Coarse Particulate Matter) and VOC (Volatile Organic Compounds) Detectors (AQI, CO2, PM2.5, PM10, VOC, T+H)


Features:
This portable air quality monitor is designed for real-time environmental monitoring at home, in offices and other indoor spaces, and it can also be used outdoors. The device displays PM2.5 and PM10 fine particulate concentrations, carbon dioxide (CO2) levels, volatile organic compounds (TVOC/VOC), as well as temperature and relative humidity, while overall air quality is shown in the AQI (Air Quality Index) format.
The unit is powered via a USB Type-C connector and turns on automatically when connected to a phone, computer, power adapter, power bank, or any other 5V source. For easier connection and flexible use, the USB Type-C plug is rotatable and can be set at 0°, 90°, or 180°, making it convenient to adapt to different setups.
Operation is simple and intuitive using the touch control at the top of the screen: a short tap switches between parameter screens, a long press rotates the display 90° counterclockwise, a double tap toggles the temperature units between Celsius and Fahrenheit, and pressing for about 8 seconds starts network reconfiguration.
The device supports connection via the Tuya Smart or Smart Life app (Wi-Fi, Bluetooth), allowing convenient data monitoring and integration into the Tuya ecosystem. When using the app, alert notifications are supported when readings deviate from the set thresholds.
For more accurate readings, it is recommended to power on the device in a clean environment, avoid holding it in your hand during measurement, keep it away from heat/cold sources and direct sunlight, and allow about 20 minutes for the readings to stabilize.
Note: the device is not water-resistant, and pressing or covering the sensor area may affect sensor performance.
The air quality monitor comes with a user manual, a USB Type-C (F) to USB Type-A cable, a wrist strap, and a storage bag.
