NOTE: First enable 'Notifications' in your Windows PC. (Click on the Clock icon, at the right corner in the status bar and turn off the 'Do not disturb' button.  Web link: plyer-notifications-are-not-visible

#Save this  Python program as 'BatteryNotifier.py' in your 'Users' folder, and run this program in DOS #prompt, and keep the DOS window open as long as you are working on your PC.

# Install and Import the 'psutil' module, for accessing info on running processes and system utilization.

# Install and Import the 'plyer' module, for accessing features of the Hardware, like displaying Notifications on the Desktop.

 ------------------------------------------------------------------------------------------------------------

import psutil

from plyer import notification

import time

import sys

import atexit

import signal

#To handle killing the process with kill or Ctrl+C.

def kill_handler(*args):

    print("BatteryNotifier is turned OFF")

    sys.exit(0)

signal.signal(signal.SIGINT, kill_handler)

signal.signal(signal.SIGTERM, kill_handler)

 

print("Battery Notifier is ON!!")

 

#from psutil we use the sensors_battery.

while(True):

    battery = psutil.sensors_battery()

    percent = battery.percent

    if percent < 70:

        notification.notify(title="Recharge battery!! ", message=str(percent)+"% Battery remaining", timeout=30)

        

        time.sleep(35)

        

        if battery.power_plugged:

            print("Power is plugged IN")

        else:

            notification.notify(message = "Power is plugged OUT", timeout=30)

        

    if percent > 97:

        notification.notify(title="Battery Full!! ", message=str(percent)+"% Battery remaining", timeout=30)

        

    

    #after every 5 mins this loop will iterate & show the respective notifications as long as anyone of the battery conditions is met.

    time.sleep(60*5)

     

    continue
