This is a 5V 4-Channel Relay interface module, for controlling various appliances, and other equipments with large current. It can be controlled directly by microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430) TTL logic.
Guide for Relay Module with Arduino - Random Nerd Tutorials
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.

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.
ArduinoBasics: 4 Channel 5V Relay Module Tutorial - YouTube
Opto-Isolated 4 Channel Relay Board. Please note: Large Quantities may have a longer lead time. Each relay draws about . 08A (80ma) so about 4 relays are the maximum you should run from the Arduino +5V supply. (Running from USB it may be less). More than 2 relays: we recommend you use a separate 5V supply for the relays.
