Design of remote interactive system based on Internet of Things

With the progress of science and technology and the continuous improvement of people’s living standards, communication equipment has brought people closer to each other. At the same time, people have higher requirements for the way of interaction in different places. Based on the rapid development of Internet of Things technology, this paper designs a set of remote interactive system using Alibaba Cloud Internet of Things platform.This system is composed of STM32F103C8T6, ESP32-CAM and ESP8266 (CP2102). STM32 is fixed in the interactive area, and ESP32-CAM and ESP8266 (CP2101) are set on the movable trolley. Peripheral sensors mainly STM32 use DHTII temperature and humidity sensor, BH1750 light brightness sensor and capacitive soil humidity detection sensor. The ESP8266 microcontroller controls the trolley movement and the four degrees of freedom rotation of the camera. The ESP32-CAM microcontroller mounted on the trolley can transmit images to users in real time. This system is economical, practical and stable, so that users can better experience the happiness brought by the interaction between different places, and can achieve good results in practical applications. It has certain production value and broad application prospects.
