Home Automation

How home automation can save you money

Investing in brand new energy efficient appliances may seem expensive at first, but within just a few years you could have made back the money from the savings on your annual energy bill. Especially if you invest in ultra-modern appliances that are connected and can communicate with one another.

KNX System

A KNX home automation system, for example, can allow your home lighting to become more intuitive. Rather than having to leave artificial lighting switched on when it is not in use – for example, if you leave a room and forget to turn it off, or you want to leave one on so you can see in the morning – the system can adjust the lights depending on your behaviour. A timer system can tell the lights when to turn on, turn off or dim to a low, energy saving light. The system can also communicate with blinds and shutters to allow sunlight into the home at a certain time of the day when it is bright enough that artificial sources of light are no longer necessary.

What is the KNX system?

KNX Standard

KNX, an abbreviation of Konnex, is an open standard (see EN 50090, ISO/IEC 14543) for commercial and domestic building automation. KNX devices can manage lighting, blinds and shutters, HVAC, security systems, energy management, audio video, white goods, displays, remote control, etc. KNX evolved from three earlier standards; the European Home Systems Protocol (EHS), BatiBUS, and the European Installation Bus (EIB or Instabus).

KNX Architecture

KNX devices are commonly connected by a twisted pair cable and can be modified from a controller. The bus is routed in parallel to the electrical power supply to all devices and systems on the network:

  1. Sensors  (e.g. push buttons, thermostats, anemometers, movement) gather information and send it on the bus as a data telegram;
  2. Actuators (dimming units, heating valves, displays) receive data telegrams which are then converted into actions; and
  3. System devices and components (line couplers, backbone couplers)

Motion Detectors: How They Work, How To Choose—& Why You Need One

, 0

What’s the best way to make sure no one’s sneaking around your house at night? That’s a no-brainer—a motion detector would have that creep behind bars in no time. But what kind of motion detector is right for YOUR home? That one’s trickier. With so many types and technologies, you might be tempted to throw your hands up and try your luck with a baseball bat—but don’t give up just yet! Here’s a handy breakdown to help you get the most effective protection for your lifestyle, without getting bogged down by tech specs.

What kind of motion sensors are there?

Motion Detectors

A motion detector is the Linchpin of your home security considering that it’s the main device that detects movement in an area. When a sensor is tripped, the device sends a signal to your security system’s control panel monitoring center, highlighting the existence of a potential threat. Subsequently, this triggers an alarm.

A motion detector has less detection areas, so it is less sensitive and generally designed to detect a movement of an arm. It is best suited to high traffic areas such as hallways.

Presence Detectors

A presence detector is significantly more sensitive so it will detect finer movements such as a hand moving. They are designed for environments with low amounts of movements such as office and sitting areas.

Similarities

In both cases, as you get closer to the detector, it will become more sensitive. The mounting height will also affect the sensitivity as well as the manufacturer specified detection area.
