The most common type of remote control receiver is the IR based. It works well, but with limitations. With an IR remote control, typically, one must have a very clear line of site from the remote to the device that is trying to control. IR transmitting and receiving systems are inexpensive and are generally reliable. The carrier frequency of such infrared signals is typically in the order of around 38 kHz. In most cases, the IR signals are send only one way, in a low-speed burst for distances of up to 30 feet. Even though IR remotes are the most common due to the low cost and most of the time it used to control a single device, RF remote controls are easier to use because they do not require line of sight and do not have to be aimed at the equipment. The RF remote can also be operated from another room. RF remotes use radio frequencies that travel far and can easily pass through walls and floors and also it can control more than one device with a single remote controller. So it offers a far better range in terms of distance. In this work RF remote controller was developed to control domestic AC appliance like CFL/incandescent bulbs, fans, heaters, single phase motors, pumps, etc…enScience and TechnologyTechnologyRemote SensingAutomationRemote ControlOther
