说明：  I2C_SHT21 温湿度传感器测量 I2C 读取SHT21 温湿度传感器 SHT21驱动库有两种操作模式，适合不同操作 自动转换测量模式： 1：启动任意一个测量指令,例如测量温度执行 measureT(); 2：延时200ms 3：读取测量后的数值, autoMeasure(float * th); 该函数读取测量得出的数据，并根据数据的类型进行转化，再自动启动下一个类型的测量 指定转换测量模式： 1：先启动一次测量,例如测量温度执行 measureT(); 2：延时200ms 3：读取测量后的数值,例如读取温度执行readT();(2C_ SHT21 temperature and humidity sensor measurement I2C read SHT21 temperature and humidity sensor SHT21 driver library has two operation modes, which are suitable for different operations Automatic conversion of measurement mode: 1: Start any measurement command, for example, measure the temperature and execute measure(); 2: Delay 200ms 3: Read the measured value and Automeasure (float * th); This function reads the measured data, converts it according to the data type, and then automatically starts the next type of measurement Specify the conversion measurement mode: 1: Start a measurement first, for example, measure the temperature; 2: Delay 200ms 3: Read the measured value, for example, read the temperature and execute readt();)

说明：  锁相的意义是相位同步的自动控制,能够完成两个电信号相位同步的自动控制闭环系统叫做锁相环,简称PLL. 3种软件锁相的方法：指针归零法，先调频后调相法，调频调相同时进行法。(The meaning of phase-locked is the automatic control of phase synchronization. The automatic control closed-loop system that can complete the phase synchronization of two electrical signals is called PLL The 3 method of software phase-locked: pointer to zeros, first phase modulation after frequency modulation, frequency modulation phase modulation at the same time.)
