How to Make an Arduino Controlled Power Outlet Box
Find out how to control any 120V appliance with your Arduino. After making this power outlet box, you can use any sensor with your Arduino to switch on or off the power supplied to the outlet. Here I use a DHT11 humidity and temperature sensor to switch off a light bulb when the humidity reaches a specific point. But you can use any home appliance combined with any sensor. I’ll also show you how to modify the code for your own project.
Here’s the blog post where we go step by step into building the box and also where the sample code and diagrams can be found:
