IoT Power Relay and Arduino - Setup and Tutorial

This video shows how to set up and use the IoT power relay to control a lamp or other appliance that plugs into a wall outlet with an Arduino. You can make the appliance react to sensors or voice commands to build your own smart home device. Written instructions are available on the Science Buddies website: www.sciencebuddies.org/scienc...

Loving these new Arduino and IoT's videos.

[@NeerajSharma-ko5wv]

awesome

The DLI power strip is nearly impossible to find right now. If you're able to share a way to do the same end result with other products that are more readily available, I think many - myself included - would be interested!

[@Science.Buddies]

It looks like SparkFun carries a kit that includes the relay that isn't sold out (yet - there are only 7 left as of writing this comment): www.sparkfun.com/products/20169. The relay itself is sold out at SparkFun, but Adafruit also has it in stock: www.adafruit.com/product/2935. Hope that helps!

There are also other types of relays you can use that involve directly wiring things instead of a "surge protector" approach like the IoT power relay: www.sparkfun.com/search/results?term=relay. We generally don't recommend them for our audience, as this requires working with high-voltage wiring directly which is very dangerous if you don't know what you're doing. The great thing about the IoT relay is that it works like a normal electrical outlet so you can just plug a device into it directly, and you only need to worry about the low-voltage microcontroller wiring.

Will this work work a thermostat ?

[@Science.Buddies]

Most thermostats do not plug into a 120V wall outlet so would not be compatible with the IoT relay.

[@kejonp9302]

can that microcontroller run 24/7?

[@Science.Buddies]

Yes - as long as it has uninterrupted power, the Arduino can run continuously. Unlike a computer with an operating system, the microcontroller won't decide to download updates or restart on its own etc.
