The question is how I connect, at SLK and SDA pins the 3
sensors school gave
Hi everybody, sorry for being newbie, at the moment I'm doing an
exercise for the school, a meteo station with 4 sensors. I installed
raspbian and use it with Putty and VLC. The question is how I connect,
at SLK and SDA pins the 3 sensors school gave me (the fourth -VOC- is
serial, has its own connection). I'm not a technician and have a little manual skill, so I ignore the way to do it. The aim is to connect simultaneously the 3 sensors, by now I can only use one sensor only.
What hardware is the solution? Thankyou Marius

who made them, and what model they are.
Its unreasonable to say "I can't solder connections and can't be bothered
to read the instructions" and expect us to do your job for free.
So, at a minimum you need to tell us exactly what each sensor measures as >well as its make and model. You also need to provide working URLs for the >online documentation for each sensor.
To be useful this documentation needs to describe the hardware (datasheet >wiring diagrams, etc) in enough detail for a competent person to
understand how to connect it to an RPi and its configured. It should also >include documentation for any supporting software if this is supplied
with the sensor.

It may not be unreasonable to think that an expert would be able to give
a friendly advice to a young student and to give him some ideas to move towards the solution ... for free.

Agreed, but "I'm not a technician and have a little manual skill, so I
ignore the way to do it" sounds much more like "do it for me because I
don't want to" than "please help me learn how to do it".
I didn't say but, we (group of students) soldered all the "holes" (sda, scl...) with a comb-like metal (like this ++++), so that the pins one side coming from sensor enter the cablet whose other side connects to right pin on Rpi. This is our problem (Ithink it is the thinnest of all the problems :-) but we're still beginners), a cablet is for 1 sensor but the pins on Rpi are only 2... What is needed is a "multicablet": 1 end to the Rpi,
that divides in more ends at the other side, so the sensors can share the communication with the processor
What type of RPi do you have that you had to solder to it? All of mine came with a set of pins for connecting jumper wires

What makes me smile is it's fairly obvious from the signal names these
are I2C sensors and nobody has told him to read about I2C.
Hint: Mario, once you have read about I2C you need to find out if the
sensors have different I2C addresses. If they do then you can connect
them in parallel and you are nearly done.
Sounds more like someone who doesn't have English as a first language
to me and this not being able to express their request simply.

There, a hint on how to proceed without doing the job for the guy.
You can all do it if you try.

declaimed the following:

What type of RPi do you have that you had to solder to it? All of mine came with a set of pins for connecting jumper wires
or proto-board (for soldering a more permanent project -- these have copper in the same arrangement as a breadboard, so when the project works you just move the components to the same position on the proto-board and solder
them)
And here is one meant for direct jumpering of an RPi https://www.adafruit.com/product/1135
breakout and cable for use on breadboard
