I am using the Arduino Uno R3 and i am trying to make a small weather station, and are looking for the BME280 sensor, but for what i can see there are 2 different versions, a 4 pin and a 6 pin.
So which type should i choose and does anyone know the difference between them?
jremington:
If the product page for the six pin sensor does not explain the identity and function of the pins, don't buy it.
The purpose and identity of the four pins on the other sensor are clear.
I could never make the 6-pin version working and ultimately fried it up. In contrast, the 4-pin version is clean and started working at the very first attempt. I like it and recommend to use the bluedot library.
The 6-pin version can be used with SPI as well as I2C.
The purpose and identity of the pins is clearly marked on the other side of the pc board.
Don't forget that there are two possible I2C addresses and that the default setup of the Adafruit board (and library) is the opposite of the setup for most of the generic Chinese versions.
About the setup i will ofc use the breadboard for testing, but also thinking about making a small permernant solution if i can make it work well.
Does any of you have a sugestion of a setup? Or maybe a board that can set it all up together? I am thinking about buying the ESP8266 to make it wireless but not quite sure (-:
Just saw your post, I`m using this library as it may be of interest to you as its so damn easy, just check out the sample sketch, you cant get much easier!.

. . . Unless you have to go in and edit the 'h' file to change the I2C address. Many other libraries, including the Adafruit library, have provisions for doing this in the actual program code.

To offer suggestions we need nor information like...
How will the device be powered. Battery (what type), solar, mains etc.
How far away from the router is the device going to be. Will Wifi reach?
How often do you want to send data?
