@Blynk_Coeur gave you a pretty good example of how to do it for one sensor, if that is not enough to get you going, I suggest you do a bit of research. Read through the DOCS, work out some of the examples on the Sketch Builder, and search around this community for examples.

Also look HERE, for some helpful advice.
