I have entered webpage mentioned on your PCB. Pinout is in Chinese: This sensor seems to be analogue. V+ denotes power supply.

that it can easily operate at 5V, however I guess it may operate at 3V3 as well. G denotes GND, T denotes temperature, probably D and P are also analogue outputs, that need to be measured using ADC.
You can read your signals using ADC connected to your RPi. Such device can easily communicate with RPi using one of two interfaces SPI, I2C.

Anyway it is important to request datasheet from the distributor, so you will no how to adjust potentiometers. You may also try to hack it :D
Analogue outputs should not exceed the power supply you may try to connect them to the ADC input, but remember to connect GND on your board to GND of your ADC.
