Split sensor output

I currently have a sensor that outputs the following :- {"CurrentTemperature":32.8,"AirPressure":255} I want to split this into 2 messages of 32.8 and 255 can anyone give me some assistance please?

Not sure how you want to split them, so here are two examples

[{"id":"80f51f7.e550e6","type":"inject","z":"c74669a0.6a34f8","name":"button","props":[{"p":"payload"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"{\"CurrentTemperature\":32.8,\"AirPressure\":255}","payloadType":"json","x":80,"y":3020,"wires":[["3e8fc37d.72ac0c","3b8973dd.e363dc"]]},{"id":"3e8fc37d.72ac0c","type":"change","z":"c74669a0.6a34f8","name":"","rules":[{"t":"set","p":"payload","pt":"msg","to":"payload.CurrentTemperature","tot":"msg"}],"action":"","property":"","from":"","to":"","reg":false,"x":310,"y":2980,"wires":[["eced12ca.e27228"]]},{"id":"3b8973dd.e363dc","type":"change","z":"c74669a0.6a34f8","name":"","rules":[{"t":"set","p":"payload","pt":"msg","to":"payload.AirPressure","tot":"msg"}],"action":"","property":"","from":"","to":"","reg":false,"x":310,"y":3060,"wires":[["c0a84d3d.bbac8"]]},{"id":"eced12ca.e27228","type":"debug","z":"c74669a0.6a34f8","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","statusVal":"","statusType":"auto","x":530,"y":2960,"wires":[]},{"id":"c0a84d3d.bbac8","type":"debug","z":"c74669a0.6a34f8","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","statusVal":"","statusType":"auto","x":550,"y":3040,"wires":[]},{"id":"dd75a682.36c55","type":"inject","z":"c74669a0.6a34f8","name":"button","props":[{"p":"payload"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"{\"CurrentTemperature\":32.8,\"AirPressure\":255}","payloadType":"json","x":100,"y":2880,"wires":[["cf65bbff.663ab8"]]},{"id":"cf65bbff.663ab8","type":"split","z":"c74669a0.6a34f8","name":"","splt":"\\n","spltType":"str","arraySplt":1,"arraySpltType":"len","stream":false,"addname":"topic","x":260,"y":2880,"wires":[["808c0be9.aee96"]]},{"id":"808c0be9.aee96","type":"debug","z":"c74669a0.6a34f8","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","statusVal":"","statusType":"auto","x":480,"y":2880,"wires":[]}]

If the output is a string, then send it through the json node. This formats a javascript object out of the string.
An then send the object through the split node.
With an attached debug node you can enjoy the result.
node-red is so cool.

That's awesome many thanks!

Are you sure you need to split it? What are you going to do with the two messages?
