Home Automation Lightning Motion Sensor and Zigbee Wireless Essay

Home Automation Lightning Motion Sensor and Zigbee Wireless - Essay Example Most presence detectors have an inbuilt 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). Belkin'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. Belkin'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 Mot ion 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 automatic ally. 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).
