Abstract
Applications based on Internet of Things (”Internet of Things” - IoT) devices allow consuming and monitoring data in real time and integrating different processes. This integration of data and processes is one of the main advantages of using IoT technology in Industry 4.0. The growth in the computational power of these IoT devices has enabled their use in different applications, such as the measurement of process variables by image processing. This work aims to develop an application with an IoT device, based on ESP32 with an integrated camera, to capture images from an analog manometer of a water treatment plant in a pharmaceutical industry and generate the measured pressure value. This data will be made available on the factory supervisory for real-time monitoring through the MQTT protocol. The pressure values were made available on the factory supervisory to allow the visualization of the data in real time.
