The system uses STM32F103C8 TB micro-control unit( MCU) as the controller to obtain main current indoor temperature and humidity
fine particulate matter( PM2.5) concentration
formaldehyde and volatile organic compounds( VOCs) content through the sensor module; the data collected by each node is sent to the monitoring center through the LoRa communication module.The monitoring center fuses the received data and displays it on the LCD.If the formaldehyde or VOCs content exceeds the standard
the adjustment module will be intelligently activated; if the PM2.5 concentration exceeds the standard
the alarm device will be activated.Test show that the intelligent adjustment module has stable performance and can effectively absorb and degrade various organic substances.The system realizes the intelligent control function of monitoring
