An IOT Based Smart AC Electricity Meter with Tamper Protection An IOT Based Smart AC Electricity Meter with Tamper Protection

I decided to create a Smart AC watt-hour meter after experiencing a spike in my electricity bill that left me both shocked and curious. Each month, I tried to be mindful of my energy use, but I realized I had no clear way to track which appliances were consuming the most power or when. I also noticed that many homes and businesses around me faced similar challenges,…

Automatic AC Temperature Controller using Arduino, DHT11 and IR Blaster Automatic AC Temperature Controller using Arduino, DHT11 and IR Blaster

An AC (Air Conditioner) which was once considered to be a luxury item and was only to be found in big hotels, movie halls, restaurants etc... But, now almost everyone has a AC in our home to beat out the summer/winter and those who have it, worry about one common thing. That is their high electricity consumption and chargers due to it.  In this project we are going to…
