MQTT

The Internet of Things (IoT) enables the creation of networks between devices, people, applications, and the Internet, creating new ecosystems with higher productivity, better energy efficiency, and higher profitability. Nodes in these networks must have the ability to communicate and exchange data, which requires the use of data transfer protocols. However, choosing the right protocol for a specific use case is not always straightforward.

The proper detection and prevention of malfunctions are crucial in mitigating maintenance costs and equipment replacements for agricultural vehicles, ultimately reducing the expenses associated with crop cultivation. Predictive analytics for agriculture vehicles leverage machine learning and sensor data to anticipate equipment faults, optimize maintenance schedules, and enhance operational efficiency in the farming industry.

The issue of creating an IP camera based on the ESP-32 CAM module, and integration and transfer of images to the messenger is considered. Provision is made to ensure and increase security during data transmission and interaction with the bot. It is also proposed to create a special telegram bot, using the telegram API, to obtain images from the camera, at any time, when connected to the Internet. The efficiency of the microcontroller at a given task is analyzed. The use of MQTT transmission protocol is proposed, and its advantages for this system are considered.

This article proposes a cost effective IoT smart home security platform that delivers data in the cloud for applications. The smart security system includes a network for sensing home monitoring devices via wireless ISM communication, a home security system control controller with an Internet connection using a Wifi connection, and a backup method of notifying the user is implemented by SMS message via GSM cellular network, cloud server and applications for mobile phones on the Android operating system.
