Aiming at the application requirements and defects of current monitoring system in household environment monitoring, a wireless household monitoring system of lower energy consumption is designed based on Zigbee technology. The design takes temperature, humidity, light, illegal intrusion detection, fire detection and timely warning integrate the intelligent household monitoring system. In wireless sensor network, the nodes can be divided to terminal node and coordinator node. CC2530 is used as
