Abstract :
Nowadays the internet is becoming more and more a part of our lives and devices are more often provided with networking capabilities. The possibilities of adding networking capabilities to your device are almost endless. For example: you can switch on a lamp in your home, read a sensor, let your security camera at home call or text you when it notices a threat ... . All of these applications can be made in such a way that they can be controlled from anywhere in the world as long as there is a network connection nearby.
The network relay board is one of those devices. This device makes it possible to switch one relay (or multiple with an upgrade) on and off from anywhere you want, as long as there is a network connection to which the device can be connected.
I first did comprehensive research to find the suitable components to finalise the project.
By doing this I came to the following setup, the connection between the internet and the relay board is made possible by a WizFi630 serial to Ethernet networking chip that is connected to an 8-bit AVR microcontroller. The microcontroller will be used to switch the relay on the board.
Network relay boards already exist but there are very few if any that also integrate network switching/routing in their design. Thanks to the WizFi630 chips integrated switching circuit it was possible to equip the relay board with two network ports. This makes it possible to connect the device between a router and a PC or to make an array of multiple relay boards without the need of adding network switches.
