Abstract
Abstract
In order to further reduce the cost and power consumption of smart homes, and increase the control methods of smart homes, a smart home monitoring system based on STM32 single-chip microcomputer is designed. The system uses STM32F103C8T6 as the main control chip, which collects the data information of temperature, humidity, light intensity, PM2.5 and methane concentration sent by the sensor, supplemented by a WIFI module, and uses ESP8266WIFI communication technology to transmit the data to the platform. The system test results show that when the room temperature exceeds 26 degrees, the refrigeration relay module works. When the PM2.5 concentration exceeds 150μg/m3, the fan turns on. When the methane concentration in the natural gas exceeds 1600 ppm, the buzzer alarms and the curtain relay works. System users can monitor and display home measurement data through OLED screens, Qt interface, mobile apps, and monitor and display home measurement data. Users can remotely monitor home conditions through the mobile client APP, and realize functions such as home temperature control, environmental detection, and curtain control.
