This paper attempts to integrate the wireless sensor network (WSN) into the smart home system. To this end, a smart home system was developed based on the basic radio frequency (RF) WSN. First, the author introduced the architecture, nodes and features of the WSN. Then, the design process of the smart home system was detailed. The hardware of the system consists of such three parts as the master control, wireless transceiver and sensor terminal; the software of the system includes the basic-RF WSN program and the master module STM32 programme. After that, the established system was applied to temperature collection and control. The results show that the collected temperature agreed well with the temperature measured by the thermometer. Finally, the temperature control effect of the system was successfully simulated with a potentiometer and an LED lamp. The research findings shed new light on the design of smart homes.
