Abstract: In order to realize wireless real-time monitoring of the family safe and protect, this paper designs a wireless smart safe and protect system base on ZigBee technology. ZigBee wireless sensor network consists of CC2430 transceiver module and various detection sensors. Sensors collect the signal spread to PXA270 master control module by CC2430 transceiver module. According to the nodes signals, the host determines emergencies and informs the owner through the GPRS and Internet modules．At the same time， the system drives the camera to shoot images at the scene, and gives the alarm by sound and light．This design implements the family fire control, security alarm and remote transmission control. Test shows that this system is of alarm response fast, high reliability, easy to expand as well as easy to promote use.
