According to the theory of long-term wear and tear in gerontology, we have developed a set of IoT systems for aging at home. These include not only the IoT home system but also a GPS tracking system and smart housing devices. The IoT system is divided into two parts, the intelligent reminder system and the pre-insurance system. In the absence of a network, the hardware can also operate effectively, so that the equipment can be more suitable for different needs of the elderly. And the tracking device can give their family members peace of mind that they can easily know their location. The last smart equipment, currently only cognitive training fitness category. In the end, I hope that we can reach the home to live in the old age, and the seniors and young people can live in harmony.
