Printing them to the Serial port is recovering them, Now if you connect Arduino TX to nodeMCU RX and nodeMCU TX to Arduino RX you can try to receive them on the nodeMCU side. You will have to 'parse' those values, and store them somehow in variables that can be displayed on a webpage or posted on a page. It is possible (likely) that you may want to send the values in a slightly different way, that might make it easier to receive. Check out Serial input basics for possible methods.
Keep in mind that a nodeMCU is a 3.3v device and the Arduino is a 5v device. Although in most cases the nodeMCU's RX-pin (GPIO 3) is 5v tolerant. (if it is, that is the only pin that is 5v tolerant) Not all nodeMCU's are the same, so first try the Arduino TX to nodeMCU RX via a voltage divider.
Arduino TX -> 1K -> nodeMCU RX -> 1K -> 1K -> GND
To reduce the logic voltage level from 5v to something nearing 3.3v
If you find that you can send from nodeMCU to Arduino but not the other way, you can try it without the divider.
