Connecting grove sensor to esp8266 without using a base shield

Hey everyone,

I am an absolute beginner and I’ve purchased a Grove water level sensor. I don’t own a grove base shield, but I do have a esp8266 which I want to connect it to. Is it possible to connect the sensor to my esp8266? If so, how? The sensor has a GND, VCC, SDA and a SCL connection.

Junquito.
