If you are using node-red-node-mysql, have you looked at the documentation for that node?

If your payload is an array, then the first 4 lines should be

let co = msg.payload[0];

Same for ox, lux and temp

Also are these enter into Db as strings? If so they need to be quoted in the sql statement, or converted to numbers if numeric.
