基于无线龙的简单点对点协议，接收添加串口通信，发射节点采用DHT11温湿度传感器，在PC上用串口工具查看回传数据时请使用十六进制显示。-Long based on a simple point to point protocol wireless receiver to add serial communications, transmitting node using DHT11 temperature and humidity sensors, with a serial port on t

利用串口通信观测dht11温湿度传感器的数据-The use of serial communication observations of temperature and humidity sensor data dht11

51单片机控制，1602显示温湿度。DHT11温湿度采集(51 single chip microcomputer control, 1602 display temperature and humidity)

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
