    b = Button(button,text="모니터링 시작",command=start,width=30,height=5,activebackground="orange").place(x=143, y=50) #버튼 설정

    stopButton = Button(button,text="종료", command=button.destroy, width=30,height=5,).place(x=143, y=150)

    button.mainloop()

Вы должны создать переменную-флаг, например:

class Loop:
    def __init__(self, tk):
        self.running = True
        self.tk = tk
        Button(tk, command=self.stop, text='Stop the loop').pack()
    def stop(self):
        self.running = False
    def loop(self):
        while self.running:
            #do_stuff()
            self.tk.update()
tk = Tk()
#init()
Loop().loop()

Изучите программирование на основе событий. Надеюсь, что это полезно!
