In order to grasp the specific air quality information of the environment timely and accurately, air quality detection system was designed, which was based on the Arduino platform. This System can easily detect common atmospheric pollutants such as PM2.5, formaldehyde, CO, etc. At the same time, the data was uploaded to the mobile terminal via Bluetooth communication, and then stored in the SQLite database. It provided reliable data for later analysis of environmental conditions. When the measured data exceeded the safety threshold, a warning signal was sent to the alarm reminding module to remind the user. Experiments showed that the mean square error of the predicted value of the system was low, and accurate air pollution data can be detected in indoor and outdoor environments.
