基于STM32的5路AD采样系统，温度、电压通过串口Labview 上显示，是学习串口通讯的好例子，真的很好

STM32读取DHT11的程序，DHT11的供电电压为3---5.5V。传感器上电后，要等待1s以越过不稳定状态在此期间无需发送任何指令。(STM32 read DHT11 procedures, the power supply voltage of DHT11 to 3---5.5V. The sensor is powered on, wait for 1s to pass the unstable state during this period without sending any

基于电压，电流检测的功率计程序 用来检测电流电压频率(Power meter based on cc2536)
