Improve Your Living Environment with Our Advanced Air Quality Detector Our Air Quality Detector is your essential companion for maintaining a healthy living space. Equipped with a dedicated sensor module, it accurately detects ambient PM2.5, HCHO, TVOC, temperature, and humidity. The data is presented on a large and clear LCD display, allowing you to easily monitor air quality levels. Plus, it provides a grade indication based on the quality of the air detected. If HCHO levels exceed the standard significantly, a buzzer alert will notify you, making this device a valuable asset for any home environment. Key Features: Multifunctional Capability: Monitor PM2.5, HCHO/TVOC, temperature, and humidity in real-time anytime and anywhere. Mie Scattering Acceleration Measurement: Offers precise detection of PM2.5, capturing even the smallest particles. Temperature and Humidity Compensation Calibration: Leveraging semiconductor humidity and thermal sensors, it provides accurate formaldehyde detection. Independent Sensor with AI Intelligent Computing: Features a semiconductor gas sensor and TVOC detection module for real-time data display. Advanced SEN+ Algorithm Calibration: The high-performance chip ensures anti-interference, high sensitivity, and stable data readings. 3D Convection Design: Real-time air circulation via convective holes for precise air quality monitoring. Clear Display: Dual thousand digit large LCD screen offers clear data visibility at a glance.
