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
