The intensification of population aging and change in family structure make it difficult for the traditional elderly care model to meet people's needs for senior care services. However, with the development of Internet of Things, Big Data, Cloud Computing, Health Detection and other technologies, the emergence of intelligent elderly care model brings an opportunity to improve the quality of senior care services. Through the combination of advanced science and technology with the traditional elderly care model, the intelligent elderly care model provides more healthy, comfortable, convenient and safe elderly care services. This paper mainly analyzes the application of health detection technology in the intelligent elderly care, and proposes the existing problems of home health detection products and their countermeasures, hoping to help the improvement of the intelligent elderly care service.
