Smart Home Hardware Design based on STM32

This paper discuss the part of temperature, humidity and light intensity sensor in the smart home system based on the STM32.The system uses the DHT11 digital temperature and humidity sensor to get and send the data, and uses the BH1750FVI to perceive light intensity.The paper also discuss the transmission timing and the data format of each sensor.At the end of the paper, it is given the C code in the KEIL MDK environment.
