Abstract

Hydroponic System is a system in which farmers cultivate different plants without utilizing the soil. The authors have proposed IoT system that monitors and controls all parameters of hydroponic system like water level, pH, humidity and temperature through mobile application. In proposed system, the authors have used an ESP32 micro-controller that is controlled pump. The pump will draw water from a reservoir which is connected to a regular water line. If the water level of the reservoir falls down to a certain level, the system will send an SMS to the Farmer. The farmer can control the water line and make the reservoir full by mobile application. An LDR and DHT11 humidity sensor is used to control the light and temperature of the farm. In system, we also used pH sensor where pH sensor is a scientific instrument that measures the hydrogen-ion activity in water-based solutions and indicating its acidity or alkalinity expressed as pH.

Summary

Introduction

Nowadays agriculture is largely dependent on soil and its nutrition contents. Due to global warming and globalization, the availability of soil for agricultural purpose is decreasing and this hampers the production of different plants. Fertilizers and pesticides are needed to use to get a better crop which is damaging the environment. To solve these problems, hydroponics can be used in agriculture. Hydroponics is a method of growing plants without soil and instead
