In the last screenshot you posted the debug panel shows every message as a string of comma separated values, NOT an array.

So do you want to convert an array or split the string into separate values?

You also posted this in a category for creating nodes, for general how-to question in existing nodes please use a more appropriate category.  
Hopefully on of the super-users can move it…

If you want them as separate messages take a look at the `split` node

Values in your string are comma separated. So splitting has to be done with separator comma.  
`var output = msg.payload.split(",");`

First element of array has index 0 (zero)  
You probably get an error now as you are looking last element from index 4, but it appears to be out of range.

You are returning the numbers [temp,humidity.....]  
You should return those objects you a created [msg1,msg2, ....]

having created the msgs you need to return them not temp etc  
so

```
return [msg1, msg2, msg3, msg4];
```

where are your debug nodes attached ? - looks like you are only showing us the one on the input - not 4 on the outputs of your function...

Is your debug is still attached to your MQTT node?

Take a look at the outputs from your function node.

So your debug will only ever show the MQTT message. You need to look at the outputs of your function node.
