Data Collection and Remote Control of an IoT Electronic Nose Using Web Services and the MQTT Protocol

Area of Science:

• Analytical Chemistry
• Computer Science
• Agricultural Science

Background:

• Electronic noses utilize non-specific sensors to identify substances by aroma.
• Remote management and data collection are crucial for deploying electronic noses.
• Internet of Things (IoT) technology offers a platform for connected devices.

Purpose of the Study:

• To develop a web-based system for remote monitoring and data management of electronic noses.
• To enable secure data transmission using MQTT and VPN.
• To apply this system for monitoring rot in sodium benzoate-treated lemons.

Main Methods:

• Integration of web technologies for browser-based access to the electronic nose.
• Implementation of the MQTT protocol for data messaging.
• Utilization of a Virtual Private Network (VPN) for secure data transfer.
• Development of a system to monitor lemon rot.

Main Results:

• A cross-platform web monitoring system was successfully developed.
• Secure and efficient remote data collection and management were achieved.
• The system demonstrated capability in monitoring treated lemons.

Conclusions:

• Web technologies and IoT provide a robust framework for electronic nose applications.
• Secure protocols like MQTT and VPN are essential for reliable data handling.
• The developed system offers a viable solution for agricultural monitoring, specifically for detecting fruit rot.
