This paper presents the implementation of an Internet of Things (IoT) application that performs the Moisture level sensing through node MCU and Raspberry Pi, and data transfer to the Cloud of the Amazon Web Services or Raspberry Pi. The implementation is done using programming the Node MCU using Embedded C, Raspberry pi is Operated using Raspbian operating system and AWS EC2 Internet of Things platform based on the Node-RED tool installed on the Raspberry Pi and the AWS EC2. The Interconnection of data from the Node MCU to Raspberry Pi is done by MQTT Data Transfer Protocol and Mosquitto Protocol.

Transfer Protocol

Focusing on the characteristics of the new high secure architecture of network computer, an operating system with internal network structure is designed. The operating system contains two subkernels: local kernel and network kernel, the two subkernels run individually in two subsystems. In order to communicate between two subsystems securely, an inter-subsystem private data transfer protocol is proposed and implemented in this paper. The private protocol is a connection-oriented protocol, it can provide reliable end-to-end connectivity Protocol format and protocol connection management based on signature verification are elaborated.

Transfer Protocol

Рассмотрены вопросы разработки требований к протоколу обмена данными в системах передачи извещений о пожаре. Разработка требований связана с необходимостью организации информационной совместимости систем передачи извещений о пожаре различных производителей с автоматизированным рабочим местом диспетчера пожарно-спасательного подразделения. Предложен базовый состав информационных данных протокола обмена. Определен общий и минимально необходимый состав информационных атрибутов базы данных по объектам защиты, устанавливаемой на автоматизированном рабочем месте диспетчера пожарно-спасательного подразделения. The issues of elaboration of requirements for data transfer protocol in fire notification transmission systems are considered. The elaboration of requirements is related to the necessity of informational compatibility between fire notification transmission systems of various manufacturers and automated workstation of fire-and-rescue unit dispatcher. The basic structure of information data of the transfer protocol is proposed. The general and minimum required structure of information attributes of the database of objects of protection is determined. This database is installed at the automated workstation of the of fire-and-rescue unit dispatcher.
