Home Notification using Telegram and Raspberry Pi

In this tutorial, I’ll share with you on how to build a home notification using Telegram and Raspberry Pi. The notification will be sent to the telegram bot when a human or animal passes by. It’s quite easy to do it. Now, let’s do it!

HARDWARE PREPARATION

This tutorial use :

  1. Raspberry PI Zero WH
  2. Maker pHAT
  3. Low Cost PIR Sensor Module
  4. Jumper Wire

You can make the hardware connection based on the diagram and table below.

Connection
PIR Sensor : VCCRaspberry Pi (Maker pHAT) : 5V
PIR Sensor : GNDRaspberry Pi (Maker pHAT) : GND
PIR Sensor : SignalRaspberry Pi (Maker pHAT) : GPIO 17

Video Reference

Please refer to this video to setup the telgram bot.

Sample Code

This is the sample code used for this tutorial. Try it!

import telepot
import RPi.GPIO as GPIO
import time
import datetime
from telepot.loop import MessageLoop
PIR = 17
GPIO.setwarnings(False)
GPIO.setmode(GPIO.BCM)
GPIO.setup(PIR, GPIO.IN)
motion = 0
motionNew = 0
def handle(msg):
global telegramText
global chat_id
chat_id = msg['chat']['id']
telegramText = msg['text']
print('Message received from ' + str(chat_id))
if telegramText == '/start':
bot.sendMessage(chat_id, 'Welcome to House Notification')
while True:
main()
bot = telepot.Bot('Your Token Here')
bot.message_loop(handle)
def main():
global chat_id
global motion
global motionNew
if GPIO.input(PIR) == 1:
print("Motion detected")
motion = 1
if motionNew != motion:
motionNew = motion
sendNotification(motion)
elif GPIO.input(PIR) == 0:
print("No motion detected")
motion = 0
if motionNew != motion:
sendNotification(motion)
motionNew = motion
def sendNotification(motion):
global chat_id
if motion == 1:
bot.sendMessage(chat_id, 'Someone is at your front door')
bot.sendMessage(chat_id, str(datetime.datetime.now()))
elif motion == 0:
bot.sendMessage(chat_id, 'Nobody is at your front door')
while 1:
time.sleep(10)

  1. hi, can u make a tutorial related to LDR sensing LEDs turning on and off with the similar concept of this home notification?

  2. CODE ERROR

    Traceback (most recent call last):
