Product overview WiFi-enabled 10-in-1 air quality detector with a 1.8 inch ultra-clear color screen that displays real-time values and historical trends for indoor air monitoring. The device measures CO2, CO, formaldehyde HCHO, TVOC, particulate matter (PM0.3, PM1.0, PM2.5, PM10), temperature, and humidity, and supports remote monitoring and alarm settings through a mobile app. Key benefits and why you need it - Comprehensive monitoring in a single device makes it easy to see multiple pollutants and comfort parameters at a glance. - Four-color alarm and audible alert provide immediate, easy-to-understand feedback when air quality thresholds are exceeded, so you can take corrective action quickly. - Portable and rechargeable design with Type-C charging and a 2000 mAh battery enables use in different rooms without constant wiring. - Remote app access and historical curves let you track trends, set alarm thresholds, and link multiple devices for centralized monitoring. - Quiet dual-sided ventilation and high-precision sensors improve measurement accuracy while minimizing noise. Core features and specifications - Measurements: CO2, CO, formaldehyde HCHO, TVOC, PM0.3 PM1.0 PM2.5 PM10, temperature, humidity. - Display: 1.8 inch ultra-clear color screen with four-color visual alarm (green, yellow, orange, red). - Sensors: Built-in high-precision sensors supporting fast, efficient detection of nine parameters. - Connectivity: WiFi support and mobile app access with 2.4 GHz hotspot compatibility for remote monitoring and alarm configuration. - Power and charging: USB Type-C charging, DC 5V 1A input, integrated 2000 mAh rechargeable lithium battery, working voltage 3.7 V, working current 260 mA. - Runtime: Real-time continuous monitoring runtime typically 8 to 12 hours; when multiple parameters are measured continuously, runtime may be 6 to 8 hours. Interval monitoring or screen-off mode can extend runtime to about 40 hours, and low-power standby can reach 2 to 5 days. - Physical: ABS housing, dimensions approximately 90 x 70 x 35 mm. - Measurement accuracy: 1 PPM for applicable gas measurements. - Controls: Single press toggles Fahrenheit and Celsius, double press mutes or unmutes sound, triple press opens calibration interface, quadruple press enters screen-off status with single press to wake the display
