Feature:1. Accurate Measurement: Our air quality monitor utilizes imported DART formaldehyde sensor, laser dust sensor, NDIR infrared carbon dioxide sensor, and temperature and humidity sensor to provide precise measurements of various pollutants such as CO2, PM2.5, PM10, TVOC, and formaldehyde in indoor air. With our device, you can easily monitor the air quality in your home or office.2. Multiple Functions: In addition to monitoring air quality, our monitor also offers advanced features. By connecting it to the Tuya App via WiFi, you can conveniently check the data on your smartphone and control various household devices such as smart curtains, fans, air conditioners, humidifiers, heaters, and air purifiers. You can also use our control panel to manage ventilation systems, air conditioners, or large-scale air purification equipment using 2.4G/Lora and other solutions.3. User-Friendly Design: Our air quality monitor is designed with user convenience in mind. It features a built-in 128MB memory card for storing data, ensuring that you can access past measurements whenever needed. The device operates at a voltage of DC 5V/2A and emits a sound level of 85dB (3M). Its working temperature ranges from 0C to 50C, and it can function under humidity levels of 0-95% without condensation.4. Wide Measurement Range: With a measurement range of 400-5000ppm, our monitor can accurately detect carbon dioxide levels in the air. It can also measure various pollutants such as PM2.5, PM1.0, pollen, TVOC, temperature, and humidity. This comprehensive range allows you to have a thorough understanding of the indoor air quality and make informed decisions to create a healthy living environment.5. Reliable Accuracy: Our indoor air quality meter provides high accuracy measurements with a precision of 1ppm. This ensures that you receive reliable information about the pollutants present in your surroundings, allowing you to take appropriate actions to improve the air quality and safeguard the health of yourself and your loveSpecification:Features:Accurate Measurement: Our air quality monitor utilizes imported DART formaldehyde sensor, laser dust sensor, NDIR infrared carbon dioxide sensor, and temperature and humidity sensor to provide precise measurements of various pollutants such as CO2, PM2.5, PM10, TVOC, and formaldehyde in indoor air.
