Design of the Ultrasonic Ranging System based on the Internet of Things

This paper introduces an ultrasonic ranging system based on the Internet of Things, which uses STM32F407ZGT6 as the main control chip, uses HC-SR 04 ultrasonic sensor for distance measurement, DHT 11 temperature and humidity sensor monitors the environmental temperature and humidity, and communicates with Ali Cloud Internet of Things platform through ESP8266 Wi-Fi module.The system design aims to provide a low-cost and efficient real-time monitoring and remote control of environmental data, which is suitable for intelligent home, industrial automation, environmental monitoring and other application scenarios.
