51单片机利用单个IO口读出温湿度传感器的数据。附件为基于51单片机的蓝牙遥控代码，其中从217行为完整的DHT11单个IO口读取数据代码方法。自己编写的代码，可靠。可以验证。(51 SCM uses a single IO port to read temperature and humidity sensor data. The attachment is a Bluetooth remote control code based on 51 single-chip microcomputer, which reads the data code from the 217 complete DHT11 single IO port. Write your own code, reliable. Can verify.)
