Crop-Dependent Automatic Water Irrigation and Rainwater Harvesting System

Abstract

A Crop-Dependent Automatic Water Irrigation and Rainwater Harvesting System is presented in this research. It uses crop-specific moisture requirements and real-time environmental data to optimize irrigation. The system uses an ESP32 microcontroller, which is connected to measurement the sensors data and to operate the water pump. A push button interface is added through which the farmer can manually select from four crop types, each of which is indicated by an LED. And a two-channel relay is used through which two motors are operated. Which enables remote monitoring and control through the Blynk internet of things (IoT) platform. The method avoids over-irrigation, guaranteeing effective water use and resource conservation, by modifying irrigation according to crop requirements and soil conditions.
