6.1 Introduction to project
Aim of the Experiment :
To make Home Security System using NodeMCU and Telegram.
Minimum Requirements :
ESP8266 (read Best ESP8266 development boards)
PIR motion sensor
Breadboard
Jumper wires
Schematic diagram :
For this project you need to wire a PIR motion sensor to your ESP8266 board. Here, we’re wiring the PIR motion sensor data pin to GPIO 14. You can use any other suitable GPIO. (Read ESP8266 GPIO Guide).
Working :
Here’s an overview on how the project works:
You’ll create a Telegram bot for your ESP8266.
The ESP8266 is connected to a PIR motion sensor. When the sensor detects motion, the ESP8266 sends a warning message to your telegram account.
You’ll be notified in your telegram account whenever motion is detected
This is a simple project, but shows how you can use Telegram in your IoT and Home Automation projects.
The ESP8266 will interact with the Telegram bot to send messages to your telegram account. Whenever motion is detected, you’ll receive a notification on your smartphone (as long as you have access to the internet).
