    The method of connecting the USB serial port module to the humidity module is:. Connect the module and the USB-TTL, and then plug it into the computer. The connection method of the module and the USB-TTL is: The VCCTX RX GND of the module is +3.3V of the USB serial port module RX TX GND should be connected correspondingly. Note that TX and RX need to be crossed, that is, TX is connected to RX. RX is connected to TX.
    Connect the USB-TTL module to the computer and turn on the host computer. After installing the driver CP210X or CH340 corresponding to the serial port module, you can query the corresponding port number in the device manager.
