Tkinter Serial data on multiple pages - python-3.x

Question

I am using Python3 with TKinter and have run into an issue, even after reading the forums and the TKdocs website I am still making no headway. I am receiving temperature readings via my com-port. My program so far has a Start page and a page one with a graph on it that updates with every reading. So the question is how can I print the sensor data on page one as well, I am new to tkinter.
I will post the code below any advice welcome.

At first I misunderstood the question, so now I am rewriting the answer. If you still have some doubts or this is not what you were expecting, just comment below. I'll try my best to help. Also, I don't have an arduino to check this for.
I have made the following changes to your code:
class StartPage(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
#Page Labels
label = tk.Label(self, text=(""" D.O :
"""), font=LARGE_FONT)
label.grid(row=100, column=20, sticky="nsew")
label = tk.Label(self, text=("""<Sensor reading here>
"""), font=LARGE_FONT)
label.grid(row=100, column=30, sticky="nsew")
label = tk.Label(self, text=(""" TEMP :
"""), font=LARGE_FONT)
label.grid(row=100, column=40, sticky="nsew")
label = tk.Label(self, text=("""<Sensor reading here>
"""), font=LARGE_FONT)
label.grid(row=100, column=50, sticky="nsew")
# Reading data from the arduino
def DataRead():
msg = arduinoData.read(arduinoData.inWaiting()) # read everything in the input buffer
print ("Message from arduino: ")
print (msg)
button1 = ttk.Button(self, text="Print arduino data",
command=lambda: DataRead())
button1.grid()
#Go to Page1 button
button1 = ttk.Button(self, text="Page1",
command=lambda: controller.show_frame(Page1))
button1.grid(row=100, column=60, sticky="nsew")
