Objective

To develop a module that enables remote control of an existing irrigation system via the Internet. The device must connect using Wi-Fi and communicate with the irrigation system via the Modbus protocol.

Solution

We developed and produced a Wi-Fi-enabled module based on the Espressif ESP32 microcontroller. Communication between the user and the controller is handled through the MQTT protocol. In addition, we created a dedicated Android mobile app that allows users to:

• control the irrigation system remotely,
• monitor device status in real time,
• interface with the system via an MQTT–Modbus converter.

This solution combines modern wireless communication with robust industrial integration — making traditional irrigation systems smarter and more accessible.
