Smart Home

introduction smart home feature allows the users to monitor various parameters such as flood, humidity, temperature, smoke, door on/off status, lights on/off controls, and others for your home users can program these devices for scenes, automation, and schedules also, these smart home devices can be monitored or controlled by the users using the x home application types of smart home devices zigbee and z wave smart home devices are used for the smart home feature of the product z wave provides a longer range than zigbee the z wave range is 100m line of sight whereas the zigbee is only 20m 1\) z wave devices z wave is a protocol that is used for communication between devices for home automation it allows low latency communication which is reliable for smaller data packs with a data rate speed of 100 kbit/second or 1ghz it uses for signaling and control and utilizes mesh topology that supports 232 nodes in a network with an operating frequency of 908 42mhz which differs in various country regions it differs from the various country region 2\) zigbee devices zigbee communication is specially built for control and sensor networks on ieee 802 15 4 standard for wireless personal area networks (wpans), and it is the product of the zigbee alliance this communication standard defines physical and media access control (mac) layers to handle many devices at low data rates these zigbee’s wpans operate at 868 mhz, 902 928mhz, and 2 4 ghz frequencies the data rate of 250 kbps is best suited for periodic as well as intermediate two way transmission of data between sensors and controllers zigbee devices z wave devices data rate 250 kb/s data rate 40 kb/s power consumption 40 ma power consumption 2 5 ma range 10 20 meters range 30 65 meters operates at 2 4 ghz operates at 908 mhz chips and modules available from multiple manufacturers chips only sold by silicon labs variable certification process strict certification process supports over 65,000 end nodes supports over 232 end nodes more difficult to configure and set up more user friendly and easier to set up more cost effective more expensive than zigbee
