One of the most cost effective methods of controlling devices within your home is using Radio Frequency (RF) transmitters and receivers. Since no wiring is necessary, this method of control is perfect for retrofitting existing homes. Over the years, the cost of these very compact devices and the modules they control has dropped dramatically. For a few dollars you can build an RF controlled automation system that manages lighting in several areas of your home. If you are new to home automation a simple keychain remote system is the place to start. Browse our wireless transmitter systems below for more information.
