With more than a decade of dense researches and development, wireless sensor network (WSN) technology has been appearing as solution to many applications. This thesis concerns of designing a wireless sensor network system which has been developed using open-source hardware platforms, ZigBee and Raspberry Pi. This design has advantages of low power consumption, low-cost and scalable in terms of the type of sensors and the number of sensor units that makes it well suited for a wide range of applications related to sending and receiving data. Although use of Raspberry Pi in the design, make it flexible, cheaper and full allocation. Python code has been used in programming the components to get a smaller code and avoid errors in programming and can be developed rapidly in the future. The choice of Raspbian operating system for Raspberries was to have a highquality, stable and scalable operating system in which supported by Raspberry
manufacturer company. Raspberry Pi act as a base station for ZigBee protocol in the wireless sensor network and collects the data from different sensors, and provide multiclients services including data display. As future development, data can be seen remotely at the base station via website.
