IoT Smart Garage Door Opener using Raspberry Pi
IoT Smart Garage Door Opener using Raspberry Pi

 

In this age of IoT (Internet of Things) where everything can be controlled remotely using your smartphone, why to carry keys with you. There are lots of technologies to support wireless controlling of devices like RFIDBluetoothWi-FiLoRa. We previously built some door alarms and door controlling circuit to open and close the door wirelessly:

Components Required

  1. Raspberry pi board with Raspbian installed in it
  2. Relay Module
  3. Connecting Wires

It is assumed that your Raspberry Pi is already flashed with an operating system and is able to connect to the internet. If not, follow the Getting started with Raspberry Pi tutorial before proceeding. Here we are using Rasbian Jessie installed Raspberry Pi 3.

 

Here External Monitor using HDMI cable is used as display to connect with Raspberry Pi. If you don’t have monitor, you can use SSH client (Putty) or VNC server to connect to Raspberry pi using Laptop or computer. Learn more about setting up Raspberry Pi headlessly here.

Connect the Garage door opening mechanism to the output of the relay. Here we have just connected an LED with relay for demonstration purpose.

Flask Setup in Raspberry Pi for Controlling Garage Door

 

Here, we have created a web server using Flask, which provides a way to send the commands from webpage to Raspberry Pi to control the Robot over the network. Flask allows us to run our python scripts through a webpage and we can send & receive data from Raspberry Pi to web browser and vice versa. Flask is a microframework for Python. This tool is Unicode based having built-in development server and debugger, integrated unit testing support, support for secure cookies and its easy to use, these things make it useful for the hobbyist.
