Data transmission can be completed through the host computer software;Acrylic clear case shell, high transmittance to be looked through;Built in for ARM 32 bit processor, accurate detection & system fluency 2.8inch TFT screen, colorization display, wide angle vision up to 180 degree;High sensitivity sensor ensures the high accuracy in data collections;Semi-closing design performs excellent in heat radiation, long-life use Multipurpose in air quality detection in PM1.0, PM2.5, PM10.0, AQI, temperature&humidity, suspended particulate matter;Real-time detection results will be shown on screen in corresponding colors related to collected datas Lightweight, easy to use and be a straightaway in data interpretation;Power supply in DC 5V universal, usb socket, car charger, power bank, etc;Suitable for home/office and car or part scope on air quality detection Font color: Multi Colors Resolution Ratio: 320x240 Operation Current: 1-2A Temperature Measure Range: -20 to 60 Celsius Accuracy: +/- 0.1 Celsius Language Version: English Working Principle: Multi-angle Scattering Detection, irradiation in the suspended particulate matter in the air and generate scattering. Scattered light will be collected in a specified angle at the same time. According to the scattering intensity, time-varying curves can be obtained through the sensor. Being processed by the microcomputer processor, equivalent particle diameters and the number of suspended particulate matter with different sizes in per unit volume can be obtained. colour: transparent Material: acrylic size: Approx. 8.5x6.5x3.7cm/ 3.35x2.56x1.46inch Package Contents: 1 x PM2.5 Air Quality Detector 1 x USB Cable Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
