The Industrial IoT is one of the key technologies to improve industrial production efficiency. The entire production process usually involves multiple production regions and numerous smart devices (sensors and actuators). The efficiency of the Industrial IoT is limited by this strong coupling relationship between the subsystem and the sensors and actuators. In this paper, to unleash the potential of Industrial IoT, a safe and reliable data sharing mechanism of sensors and actuators is proposed. We deployed distributed identity authentication and data proxy services in various regions. In the device authentication process, we used identity-based encryption algorithms, and we solved the trust problem between different regions by introducing a private blockchain. In addition, we designed the model of device capability (MDC) to describe the device, enabling it to be shared with a standard interface. Finally, we conducted many performance tests on the proposed mechanism. The test results verified the effectiveness and efficiency of the proposed mechanism.

Neste artigo apresenta-se o uso de um microcontrolador Raspberry Pi como um conversor de protocolo Modbus para MQTT. Essa conversão permite que o Raspberry Pi se comunique com um Controlador Lógico Programável (CLP) utilizando o protocolo Modbus enquanto envia dados para um servidor MQTT. O objetivo desse sistema é permitir que uma rede industrial legada cujos dados estejam disponibilizados apenas via protocolo Modbus possa se integrar a uma rede mais moderna usando um protocolo aderente ao modelo recomendado pela Indústria 4.0 (MQTT). Este artigo discute, então, o desenvolvimento e validação de um protótipo IoT-MQTT para interfaceamento entre um Simulador Físico controlado por um CLP legado baseado em protocolo Modbus e uma infraestrutura de comunicação aberta e aderente às recomendações da Indústra 4.0, e que pode ser utilizado em uma ampla gama de aplicações industriais.

Due to the problem of drinking water scarcity in different cities around the world, there are innovative proposals to automate garden irrigation in homes, to reduce drinking water consumption. For this research, a sample of 68 inhabitants of the Region of Arequipa - Peru has been surveyed to know the common habits in the irrigation of the gardens. From this data, two systems have been implemented in two average gardens using the Arduino UNO board (integrating with the Ethernet Shield) and the NodeMCU, each proposal integrates soil moisture sensors, water flow sensor, and actuators, such as the solenoid valve and the relay, besides centralizing the information through an IoT System (Home Assistant or Adafruit IO). This has managed to establish a comparison of both, generating a discussion according to the advantages and disadvantages addressed by each proposal and obtaining a saving of potable water in the irrigation of plants.
