Data transmission can be completed through computer software; Acrylic clear case shell, high transmittance for clear visibility; Built-in ARM 32-bit processor for detection and system fluency; 2.8-inch TFT screen, color display, wide viewing angle up to 180 degrees; High sensitivity sensor ensures high accuracy in data collection; Semi-closed design enhances heat dissipation for long-life use; Multipurpose air quality detection for PM1.0, PM2.5, PM10.0, temperature, humidity, and suspended particulate matter; Real-time detection results displayed on screen in corresponding colors based on collected data; Lightweight and easy to use with clear data interpretation; Power supply: DC 5V universal input via USB socket, car charger, or power bank; Suitable for home, office, and car use for air quality monitoring; Font color: Multi-colors; Resolution: 320x240; Operating current: 1-2A; Temperature measurement range: -20 to 60C; Temperature accuracy: 0.1C; Language version: English; Working principle: Multi-scattering detection laser irradiates suspended particulate matter in the air, generating scattered light. Scattered light is collected at a specified angle. Based on scattering intensity and time-varying curves from the sensor, the microcomputer processor calculates equivalent particle diameters and the number of suspended particles of different sizes per unit volume; Color: Transparent; Material: Acrylic; Size: 8.5 x 6.5 x 3.7 cm / 3.35 x 2.56 x 1.46 inches; Package contents: 1 x PM2.5 Air Quality Detector, 1 x USB Cable; Only the items listed are included; Note: Lighting and display differences may cause slight color variation between the image and the actual item. Measurement error allowed: 1-3 cm.
