Design of Smart Home Monitoring System for Elderly Care Based on Raspberry Pi

In the current social environment, young people are getting busier, which results in them having no time to take care of the elderly at home. The elderly need to pay attention to health problems, so it is of great significance to design an intelligent home environment and monitoring system for the elderly. This paper developed a human heart rate and blood-oxygen collection terminal system based on Raspberry Pi, Alibaba Cloud IoT (Internet of Things) Platform and sensors, and had the function of monitoring the temperature and humidity in the elderly's home. The data collected from sensors are processed by the Raspberry Pi chip and sent to the IoT platform, and finally presented to the public in a visual form. The guardian can control the operation of the air conditioner in the home according to these data so that the elderly can have comfortable living conditions.
