Remote Control Transmitters & Receivers By Whome

You can overcome the `neutral problem', and get increased flexibility, with wireless devices. Being wireless, they need a transmitter and a receiver; additionally the wire-free part (the transmitter) will need battery power. There are two types of receiver: infra-red and radio frequency, RF devices offer better battery life in the transmitter, but are otherwise not very useful (in my experience) as they need line-of-sight between the transmitter and the receiver. With a radio system, the receiver can be mounted anywhere in the house that is within range, and need not be visible (I have mine behind a cupboard). The range of most of these devices is such that the transmitter will work anywhere in an ordinary-sized house, and at least part of the grounds as well. Transmitters are available in a number of flavours. `Replacement light switches'. The transmitter replaces a standard wall-mounting light switch, whose wiring thus becomes redundant. One-gang and two-gang devices are available and, owing to their small size, they do look OK as a lightswitch. However, most of these devices sacrifice range for increased battery life; many have a range of only a few meters. This means that you must mount a receiver fairly close by. If this scheme is widely used, you will end up with a large number of receivers. This is not a technical problem, but will be expensive. Handsets. An X10 remote control handset looks like the remote control device that you might get with a television or video player. However, if it is radio-based -- rather than infra-red -- then it will be usable anywhere in the house. A number of devices (e.g., MK19) are available that combine X10 control with standard infra-red remote control, so can be used to control television and hi-fi as well. Control panels. Devicesprovide the same facilities as plug-in controllers, but without the need for plugging in. Although portable, they are large and therefore less suitable for mobile operation than handsets. Key-ring devices. These are very small transmitters designed to be carried on a key-ring. They normally allow one or two devices to be controlled. If they are radio devices they will work from outside the house. This allows lights, locks, etc., to be controlled from outside. Wireless security sensors, e.g., MS13 motion sensor or door sensor are intended for wireless security systems. Whome Profile Whome Website
