Vehicle Air Quality Monitor with PM2.5 Sensor LED

1 Intelligence is derived from ARM microcomputer processor. ARM chip is 10 times faster than similar products using 8-bit computing, which bring more accurate detection and smoother system 2 No need to calibrate, USB power to use without needing of warm up 3 Equipped with fan, which guarantee good heat dissipation effect 4 Using electrochemical principles, multi-layer special glass fiber microporous filtration can effectively eliminate the interference of ethanol, CO, etc. 5 The monitoring function is realized by electrochemical principles, and data processing algorithms are added to obtain stable and accurate data 6 Thousandth display, users does not need to calibrate, the reading can be read after the boot is stable
