Smart Switch - Automatically Turn On the Fan when room is hot | Home Automation with Arduino

This video is the second part of my DIY Home Automation series. I will show you how to connect a 220 Volt AC electric fan to this system. The fan will automatically turn on when the temperature in the room gets hot.
If you want to check out how I set up the temperature and Humidity sensor, here is the video link - • Temperature and Humidi...

👉👉WHERE TO GET THE CODES
To consolidate all of my codes as well as other resources I used in all of my builds, I have created an Educational Group on Facebook. Codes are uploaded under the "GUIDES" section.

Hi, nice job but I have a question: why using batteries to power the arduino whereas you have 220V power available? So why not using a 220V to 5V transformer to power the arduino ?

I needed the battery bank as a power source for the other sensors and components that need 3v and 5v
