PyQt5 GUI Application

This project is a PyQt5 GUI application that demonstrates a simple home page with two buttons: RGB Feed and Thermal Feed. The application follows the Model-View-Controller (MVC) architecture, separating the concerns of data management, user interface, and application logic.

Components

Controllers

• home_controller.py: Manages the interaction between the view and the model. It handles button clicks for RGB feed and Thermal feed.

Models

• feed_model.py: Contains the data and logic related to the RGB and Thermal feeds.

Views

• home_view.py: Creates the GUI for the home page, including buttons for RGB feed and Thermal feed.

Main

• main.py: The entry point of the application that initializes the application, creates instances of the model, view, and controller, and starts the main event loop.

Requirements

Ensure you have PyQt5 installed in your environment to run the application. You can install it using pip:

pip install PyQt5

Usage

To run the application, execute the main.py file:

python main.py

This will launch the GUI, allowing you to interact with the RGB and Thermal feed buttons.

Additional Notes

This project serves as a foundation for further development and can be expanded with additional features and functionalities as needed.

SMALL PROGRAM ON PID HEATER CONTROLL FOR REFF

import time import numpy as np import cv2 # For processing thermal camera feed import board import busio import adafruit_mlx90640 # Example thermal camera (MLX90640) from simple_pid import PID # Install using: pip install simple-pid

Adjustable Parameters

TARGET_TEMPERATURE = 70.0 # Desired temperature (in °C) PWM_MAX = 255 # Max PWM value (adjust based on hardware) PWM_MIN = 0 # Min PWM value

Initialize I2C for Thermal Camera (MLX90640 as an example)

i2c = busio.I2C(board.SCL, board.SDA, frequency=400000) mlx = adafruit_mlx90640.MLX90640(i2c) mlx.refresh_rate = adafruit_mlx90640.RefreshRate.REFRESH_16_HZ

Initialize PID Controller

pid = PID(1.5, 0.1, 0.05, setpoint=TARGET_TEMPERATURE) pid.output_limits = (PWM_MIN, PWM_MAX) # Restrict heater power

Function to get average temperature from thermal camera

def get_average_temperature(): frame = np.zeros((24*32,)) # MLX90640 resolution (24x32) mlx.getFrame(frame) return np.mean(frame) # Average temperature of the scene

Function to set heater output (PWM)

def set_heater_power(power): power = int(power) # Convert PID output to integer print(f"Heater Power: {power}") # Replace with actual PWM control

Main Loop

while True: try: # Read temperature from the thermal camera current_temp = get_average_temperature() print(f"Current Temp: {current_temp:.2f} °C")

    # Compute PID output
    heater_power = pid(current_temp)

    # Apply heater control
    set_heater_power(heater_power)

    time.sleep(0.5)  # Adjust loop frequency based on system response

except KeyboardInterrupt:
    print("Stopping heater control.")
    break
