Due to the demand for nursing care of elderly, a health care scheme in nursing homes is proposed based on ZigBee wireless communication technology,design a cost-effective, low-power-consumption ZigBee wireless monitoring system. Each node of the system is based on CC2530, collects the vital signs of elderly by controlling the pulse sensor, temperature sensor of DS18B20, blood pressure sensor of XGZP6847. Data is monitored and analysed in custody center。If the data exceeds the range, the system will give a voice prompt, and announce nursing workers. The experimental results show that the system can effectively improve the level of nursing home care.
