Channel 5V Relay Shield Module - SunFounder
Channel 5V Relay Module 10A This small 4 Channel Relay Board works from a 5V supply for the relays and between 1V and 5V for the switching signal. It uses a transistor and opto-isolator to switch the relay on so can be connected directly to a microcontroller pin.
Home Automation How to Add Relays to Arduino
The simplest solution for on/off Home Automation is to use pfodDesignerV2 to design your control for upto 4 switches and then use a Arduino Uno + Bluetooth module + 4 channel relay board powered by a USB power supply and controlled by pfodApp and, if switching mains power, have an electrician wire it in.
