Adults spend 80% of their time indoors every day, so the quality of indoor air is closely related to people's health and quality of life.In this project, an indoor environment monitoring system is designed for indoor air quality. Data interaction between the system and the indoor air monitoring system is carried out by means of wireless transmission, so as to monitor indoor PM2.5 concentration, temperature and humidity in real time through mobile phones.Realization function: For the collection of various parameters of the home environment, the collected environmental parameters will be transmitted to the main control device through the RS-485 circuit, using the RS-485 circuit to transmit data, can collect data for different positions of the indoor, aiming at faster and more accurate detection of indoor air condition.
