That is where you post when you are willing to pay someone to do your work.
If you are not willing to pay, then try to do it yourself.
There are likely tutorials on each one of those sensors. Try one, all by itself.
If it works, great, try a tutorial for the next.
If it does not work, come back and post your code, post a wiring diagram and describe what it DID do.
You will find that this gets you much more help than begging for free work.
Cross-post.
