This chapter reviews a number of the application scenarios in which ZigBee devices can increase efficiency and/or reduce cost. Full ZigBee protocol implementation has the advantage of reliable mesh working capability. However, if the application is simple, it might be possible to implement only IEEE layers. Home Automation Home automation is one of the major application areas for ZigBee wireless working. In this section, a number of these use cases are reviewed. The typical data rate in home automation is only 10Kbps. Figure shows some of the possible ZigBee applications in a typical residential building. Most of the applications shown in Figure are briefly reviewed in this chapter. Security Systems A security system can consist of several sensors, including motion detectors, glassbreak sensors, and security cameras. These devices need to municate with the central security panel through either wire or a wireless work. ZigBeebased security systems simplify installing and upgrading security systems. Despite ZigBee’s low data rate, it is still possible to transfer images wirelessly with acceptable quality. For example, ZigBee has been used in a wireless camera system that records videos of visitors at a home’s front door and transmits them to a dedicated monitor inside the house. MeterReading Systems Utility meters need to be read on a regular basis to generate utility bills. One way to do so is to read the meters manually at homeowners’ premises and enter the values into a database. A ZigBeebased automatic meterreading (AMR) system can create selfforming wireless mesh works across residential plexes that link meters with utilities’ corporate offices. AMR provides the opportunity to remotely monitor a residence’s electric, gas, and water usage and eliminate the need for a human visiting each residential unit on a monthly basis. An AMR can do more than simply deliver the total monthly usage data。 it can gather detailed usage information, automatically detect leaks and equipment problems, and help in tamper detection. ZigBeebased wireless devices not only perform monitoring tasks, they can manage the usage peak by municating with the appliances inside the house. For example, when there is a surge in electricity usage, a ZigBeeenabled electric water heater can be turned off for a short period of time to reduce the peak power consumption. Irrigation Systems A sensorbased irrigation system can result in efficient water management. Sensors across the landscaping field can municate to the irrigation panel the soil moisture level at different depths. The controller determines the watering time based on moisture level, plant type, time of day, and the season. A distributed wireless sensor work eliminates the difficulty of wiring sensor stations across the field and reduces the maintenance cost. Light Control Systems Light control is one of the classic examples of using ZigBee in a house or mercial building. In traditional light installation, to turn on or off the light it is necessary to bring the wire from the light to a switch. Installation of a new r
