Design and Implementation of Wireless Environment Monitoring System Based on STM32

Abstract

This paper first designed the overall scheme of a wireless-based intelligent environment monitoring system; this system is comprised of the following four parts: server part, client part, slave computer part, and master computer part. The master computer is equipped with a wireless transmission module and an LCD module. Slave computers are equipped with temperature-humidity sensing modules and wireless transmission modules. The server side has two major interfaces: data display and server establishment. An Android phone as the client can realize the communication between the mobile APP and server through network communication to obtain environmental data in real time. The hardware part of the system consists of wireless transmission module, temperature and humidity module, smoke module, lighting module, flame module, and LCD module. The software implementation part mainly includes the design and implementation of serial communication, the design and implementation of wireless communication, the design and implementation of collection of data acquisition in each sensor module, and the design and implementation of network communication as well as the design and implementation of display unit. With the cooperation of these four parts, we can automatically sense and control the state of the environment to realize human-computer interaction.

Internet of things with NodeMCU ESP8266 for MPX-5700AP sensor-based LPG pressure monitoring

“…IoT can be used to monitor a device or an object remotely [3], [13], for example, by monitoring gas pressure conditions. IoT technology can be accessed using microcontrollers, including Arduino, NodeMCU, and STM32 [14]- [17]. The research was designed as a gas pressure monitoring tool using the MPX-5700AP sensor.…”
