INTRODUCE
SL820 is an intelligent Internet product which is suitable for the home users, enterprise office and public institution that is used for the detection of air quality. It is designed to detect the PM2.5 particle, formaldehyde content and humiture. Otherwise, the data of detection can be displayed on the LCD screen of device and sent to Cloud Server by wireless transmission. It is very convenient to check the result of test and the historical test data by users through their mobile phone App.
