Pls, tell me how can connect with Gravity: Industrial Stainless Steel Submersible Pressure Level Sensor(0~5m) with this module ?

The function of this module is to use IIC data to output the voltage of 0-VCC.
Are you intend to power on the Gravity: Industrial Stainless Steel Submersible Pressure Level Sensor(0~5m)?
You can connect the VCC and GND out from this module and VCC to +, GND to -.

Or you just want a Digital Analog convertor?
Maybe you can take a look at:
