I have just completed making a Smart Power strip that features 2 sockets that can be independently controlled by an app as well as can be voice controlled using Alexa. The product also features a multi-colored mini lamp as featured in my earlier post that can be controlled by app too and also features voice control via Alexa. The module also has 2 master switches that can be used for completely switching off the sockets so if someone wants to use the power strip in a conventional manner without using the "smarter" ways, that option is also present.
Unfinished Mess
The project basically requires you to have basic electric networks knowledge on how AC supply works and is connected to appliances. For providing IoT ecosystem & app control, we use a microcontroller that controls a relay which controls the switching action of the sockets. The same microcontroller also controls the RGB multi color lamp.
The Finished Product
Another great feature of this project is that it's very inexpensive and you can easily extend it to a 3 or 4 socket power strip. Only additions would be the box ,sockets, switches and extra relays.
A general-purpose input/output (GPIO) is a digital signal pin on an integrated circuit or electronic circuit board(In our case, a microcontroller or arduino board) whose behavior—including whether it acts an input or output—is controllable by the user. GPIOs have no predefined purpose and are unused by default. If used, the purpose and behavior of a GPIO is defined by the user or the developer. These pins basically act as bridges to interface with the outside world. For instance, a LED can be connected to these pins as an output device or a sensor can be connected to GPIO for obtaining some input which can be processed by the microcontroller. However, these pins should be made available by the board manufacturer so that they can be used by developers and prototypers. Arduino also has many GPIO pins available for users to program and interface. The pin number and location can be found on multiple diagrams available on the internet. You can see the different pins as well as ...
In Electronics, the basic definition of a sensor is a device or a module that senses a physical parameter in the environment and converts the measured parameter into information that is usually understandable by a processor or a micro-controller. The electronic sensors we use with respected to Embedded Systems and IoT convert the physical parameter into electrical voltage or a digital logic level(which is same as voltage but only allowing 2 levels i.e. 0 and Vcc). It is very important to understand that as we human beings have senses that help us obtain information and process it, the micro-controller or processor can obtain such physical information through these electronic sensors. So knowing and understanding these sensors is very important if we want to build an application or a smart device using IoT. Our device or application via the sensors can obtain all sorts of information from the real world like temperature, pressure, concentration of variety of gases, infrared s...
Amazing project😊😊
ReplyDeleteThank you :)
DeleteSir please give some information about ATTINY 85 , 8-pin microcontroller in your future post...
ReplyDeleteDuly noted, will definitely cover it in future posts
DeleteAmazing 👍
