Most presence detectors have an in-built light sensor (lux) that will turn off the lights if there is sufficient natural light. Regulating lights with a presence detector may save up to 65% of the total cost spent on lighting energy (CP Electronics, 2013). How the system works Presence detectors also known as PIR (Passive Infra-Red) work on a principle similar to that applied in motion detectors. These devices log the thermal radiations of their environments or area under detection. When thermal radiation in the area is detected, for example, in the case of a person coming close to the sensor, the detector will convert these vibrations into measurable electrical signals which will then turn on the lights. Presence detectors utilised in controlling lighting assist in the continuous adjustment of the output of faint lighting systems. This functionality facilitates management of energy saves costs over the conventional switching systems. Presence detectors provide an automatic hands-off lighting system that combines user comfort with an optimum energy consumption (Theben, 2011). Belki’s new device called WeMo makes home automation simpler. According to the company manufacturers, the device allows the user to control home-entertainment and other applications using iOS devices. Belki’s WeMo system incorporates a number of devices that are linked to the users Wi-Fi network. The system can then be managed by an iPad app or WeMo iPhone. Unlike other home automation systems, WeMo is entirely modular, and the user can add more nodes to increase its effectiveness (Linked in, 2013). How WeMo works The WeMo Switch and WeMo Motion are the present WeMo devices that exist today. The WeMo Switch is plugged into a wall outlet and serves as a remote-controlled socket that turns connected devices on or off according to the user’s command. The WeMo Motion device is also plugged into a wall socket, and has a 6-foot power cord which links to a motion sensor. Both the WeMo Motion and WeMo Switch are linked to the wireless network of the user, and the WeMo iOS app detects these components automatically. Various home appliances can be connected by plugging them into the WeMo Switch. The appliances connected to the WeMo Switch can then be turned on or off using iOS app available in the system. Therefore, the WeMo Switch allows the user to check if certain household appliances have been turned off in order to avoid the requirement of running an entire home check. The WeMo Switches have power buttons that replace the switch on the wall socket. WeMo Switch Setup The WeMo is not available officially, but its setup is a breeze. Once turned on, the isolated WeMo device creates a wireless network named as WeMo-XXX, where XXX is the device’s ID number. The next step involves connecting the iPad or iPhone to the network, and a free WeMo app is initiated. The WeMo app will then detect the primary Wi-Fi network and pull the required data configuration automatically. The WeMo app will also ask for a Wi-Fi password to ensure the user’s network is secured. The device collects additional configuration information necessary for its operations and then links to the wireless network. In addition to the ability to remotely switch domestic devices on and off, the principal selling point of the WeMo system is its simplicity of deployment. The WeMo Switch will also come at an affordable cost of about $50, according to the company reports (Honeywell, 2013). GJD Manufacturing Limited is another leading industry in the
Name Instructor Course Date Literature Review Introduction Presence detectors are sensors designed to minimise the amount of time lights are left on unnecessarily. For instance when a room is vacated or there is adequate natural light, the lights in the building must turn off…
Researchers have been working on the development of wireless technologies for the automation of homes and different establishments since many years. It is due to the increasing desire of automation that Zigbee Alliance introduced Zigbee protocol in the domain of wireless sensor networks.
Home automation is also referred to as smart home. The word smart home was given a definition in 2003 by Housing Learning & Improvement network, which stated that a smart home is “a dwelling incorporating a communications network that connects the key electrical appliances and services, and allows them to be remotely controlled, monitored or accessed.” 1 Home automation can prevent the handicapped from becoming anxious when transiting to a health care facility (Cheek 2005).
It involves designing a system and using a microcontroller to program it. The aims and objectives of the project included detecting motion, sending output signal from the controller to motor, making a prototype of the system, creating an understanding of how a motion sensor works, as well as learning how to program a microcontroller.
It is a short–range technology and can be used to set up peer-to-peer Wireless LAN for sharing printer, fax and data transmissions. The spectrum for infrared is virtually unlimited, which presents the possibility of achieving
