I would like to connect a BMP180 GY-68 berometric sensor (I2C).

On Arduino UNO its easy, just include three libraries

Code: Select all#include <Wire.h>
#include <Adafruit_Sensor.h>
#include <Adafruit_BMP085_U.h>


connect the sensor SCL to A5 and SDA to A4 and that's it. It works.

I tried to fiend a way to make this up and running on my NodeMCU ESP8266 Dev. Board as well, but I couldn't find one.

Is this generally possible or simply not ?
