Vehicle GPS Tracking with Telegram and ESP32 on Google Maps

Hey! Today, this tutorial shows how to make a Live Vehicle GPS Tracking system using ESP32, Telegram, and Google Maps, allowing real-time monitoring of vehicle locations from anywhere in the world, and ensuring car security. In a previous version of our vehicle tracking system, we used Raspberry Pi Pico and GPS technology. While it worked well, some limits affected its performance.

In this article, we will build an advanced version of the vehicle tracking system by using Google Maps for real-time tracking. With the integration of Google Maps, you can easily see where your vehicles are at any given time.

Required Material

Here are the components and tools you’ll need:

ESP32 board
GPS module (e.g., NEO-6M)
Jumper wires
Breadboard

NEO-6M GPS module

NEO-6M GPS module is a high-performance GPS receiver. The module gets signals from GPS satellites and It uses the NMEA protocol to transmit GPS points, such as latitude, longitude, and altitude. Checkout NEO-6M GPS Module with Arduino | Tutorial

The module gives accurate GPS information for applications through UART conversation, including navigation, monitoring, and geolocation.

5Hz position update rate
Operating temperature: -40°C to 85°C
Power supply: 3.3V~5V
UART TTL socket for easy communication
Configurable baud rates: 4800 to 115200 (default 9600)
Fast start times: 38 seconds (cold start), 1 second (hot start)
Rechargeable backup battery
EEPROM for saving configuration settings
SuperSense® Indoor GPS with -162 dBm tracking sensitivity
Support for SBAS (WAAS, EGNOS, MSAS, GAGAN)

Pinout of NEO-6M GPS Module

VCC: Power supply
GND: Ground
TX: UART transmit
RX: UART receive

Connecting NEO-6M GPS Module with ESP32

GPS VCC to Pico 5V pin for power.
GPS GND to Pico GND pin for ground.
GPS TX to Pico RX pin for receiving data.
GPS RX to Pico TX pin for transmitting data.

Configure Telegram Bot For ESP32 GPS Tracking

Open Telegram and search for BotFather.

Start a chat and create a new bot using the /newbot command.

Follow the instructions to name your bot and get the bot token Note down the bot token for later use.

Find Your Telegram ID

Search for @idbot in Telegram.

Start a chat with @idbot and type /getid.

You will receive your Telegram ID, which you will use in your code

Code & Libraries

Install the necessary libraries:

Open the Arduino IDE and go to Sketch > Include Library > Manage Libraries.
Install the UniversalTelegramBot and TinyGPS++ libraries.

Replace "YourSSID", "YourPassword", "YourBotToken", and "YourChatID" with your actual credentials and Telegram details in your code.

// WiFi credentials

const char* ssid = "RaushanZeba";

const char* password = "82728378937";

// Telegram bot token and chat ID

#define BOTtoken "48726748:fsodifjsioufopsdifopsd"

#define CHAT_ID "827450947902"

After updating the code, attach ESP32 to your computer using a USB cable. Then, press the upload button in the Arduino IDE. This will flash the updated program onto the ESP32 microcontroller.

After uploading the code Open the Serial Monitor in the Arduino IDE. To Check that the ESP32 connects to the Wi-Fi network.

Send the /start command to your Telegram bot.

Use the /location command to receive a link to your vehicle’s current location on Google Maps.

Open the link https://www.google.com/maps/@25.620745,85.102699,21z?entry=ttu in any web browser to view the location of your tracker on Google Maps.
