This design has developed a multifunctional home robot environmental detection system based on the STM32F103C8T6 microcontroller. The system integrates the DHT11 temperature and humidity module, TVOC-CO2 air quality monitoring module, TJC3224T128_011R serial port screen and voice interaction module. It realizes real-time collection and processing of environmental data through the single-wire and serial communication protocols. By adopting a localized data processing mechanism, the system triggers an alarm when abnormal environmental conditions are detected. It also supports dynamic display on the serial port screen and data upload to the cloud platform via ESP8266 or WIFI. This system addresses the issues of single perception, lagging data processing and poor compatibility of traditional home monitoring devices, achieving all-weather monitoring of multiple parameters such as temperature, humidity, TVOC, CO2 and HCHO, providing real-time data support for smart homes.
