The invention relates to a PM2.5 and air humidity detection device and a system based on Arduino, wherein the detection device comprises an Arduino development board, a PM2.5 sensor, an air humidity sensor, and a Bluetooth module. The Arduino development board comprises a single chip microcomputer, the PM2.5 sensor, the air humidity sensor, and the Bluetooth module are all connected to the singlechip microcomputer, the following steps are implemented when the single chip microcomputer executes the program: reading a PM2.5 data acquired by the PM2.5 sensor, calculating a PM2.5 value based on the PM2.5 data; reading an air humidity data acquired by the air humidity sensor, calculating an air humidity value based on the PM2.5 data; and transmitting the PM2.5 value and/or the air humidity value to the outside through the Bluetooth module. Compared with the prior art, the PM2.5 and air humidity detection device and system based on Arduino is developed based on arduino ide and app inventordevelopment platform, and
