python 3, tkinter, SenseHat, how to display a updating tempreture in a label
To display an updating temperature from a Sense HAT sensor in a Tkinter label using Python 3, you can use the following approach:
Install Required Libraries:
Make sure you have the required libraries installed. You can install them using the following commands:shellpip install sense-hat
Create the Tkinter Application:
Create a Python script that initializes the Tkinter GUI and continuously updates the temperature in a label.pythonimport tkinter as tk
from sense_hat import SenseHat
import threading
class TemperatureApp:
def __init__(self, root):
self.root = root
self.root.title("Temperature Display")
self.sense = SenseHat()
self.temperature_label = tk.Label(root, text="Temperature: ")
self.temperature_label.pack()
self.update_temperature()
def update_temperature(self):
temperature = self.sense.get_temperature()
self.temperature_label.config(text=f"Temperature: {temperature:.2f}°C")
self.root.after(1000, self.update_temperature)
def main():
root = tk.Tk()
app = TemperatureApp(root)
root.mainloop()
if __name__ == "__main__":
main()
This script creates a Tkinter application with a label that displays the current temperature from the Sense HAT sensor. The
update_temperature
method reads the temperature from the sensor and updates the label text every second.Run the Script:
Run the script using the following command:shellpython script_name.py
Replace
script_name.py
with the actual name of your Python script.
The above script provides a basic example of updating temperature in a Tkinter label using Sense HAT. You can enhance the design and layout of the GUI according to your preferences.
