IoT-Based Real-Time Pneumatic Pressure Monitoring and Notification System: A Case Study in the Manufacturing Sector

In this study, the development and implementation of an Industrial Internet of Things (IoT) project for pneumatic pressure monitoring is presented. An ESP8266 module and a Danfoss pressure transmitter with a 4–20 mA current output representing pressure levels from 0 to 10 bar are utilized. The pressure sensor's current output is converted to voltage using a 230-ohm resistor and measured by the ESP module's analog pin. Remote monitoring and email notifications, facilitated by the Blynk app, enable real-time assessment of pressure levels from various sources, addressing industry challenges including manual monitoring limitations and the impact of pressure variations. Continuous natural gas (NG) pressure monitoring for gas engines and supervision of pneumatic pressure-sensitive machinery are achieved remotely, with a software implementation covering programming languages, algorithms, and data processing methods tailored for pneumatic pressure data analysis. The effectiveness of IoT-based pressure monitoring in enhancing operational efficiency and maintaining quality standards in industrial settings is demonstrated by this project.
