Design and Development of Weather Monitoring and Controlling System for a Smart Agro (Farm)
Weather plays an important role in our farming system. In greenhouse or internal farming system, weather monitoring is important. For better production and maintenance, it is important to monitor. This project is developed for forecasting weather parameters like humidity, temperature, soil moisture, and raid detection. Humidity and temperature are monitored for internal temperature. The soil is the most important part of a greenhouse. In this project, soil moisture level is monitored and controlled for maintaining soil moisture level. Rain detection is used in outside of the farm. It detects rainwater and sends a message to the server. It is monitored by using a local server. In remote routing area, it also can be monitored and controlled without physical existence. Also, it is a low-cost weather monitoring system for the agro farm. The Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. The monitoring system could be designed by using the sensor. It is useful for forecasting and data analysis process. In this project weather forecasting system is designed by using a sensor. In this project, Raspberry Pi work like a remote monitoring and controlling system for the agro farm.

1. Introduction

Weather describes the atmospheric condition at a place over a short duration of time. Weather is defining different variables, such as temperature, humidity, air pressure, and the wind. Weather or Climatic change plays an important role in human life.

Weather monitoring is important for our household, farming to the industrial environment. There has been always a huge importance of climate for human life and to develop agriculture to its observation. Nowadays, there are many automation systems and weather forecasting systems all over the world collecting the environmental parameter continuously for forecasting. Weather plays an important role in agricultural production. It has a profound influence on crop growth, development, and yields, on the incidence of pests and diseases, on water needs, and on fertilizer requirements. For more production, a farming system needs real-time monitoring and update of soil moisture, rain detection, and different data analysis [1] . The monitoring system could be design based on IoT by using Raspberry Pi [2] .

The Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. It is a capable little device that enables people of all ages to explore computing and to learn how to program in languages like Scratch and Python. It’s capable of doing everything like a desktop computer to do, from browsing the internet and can be capable to maintain external device like Arduino.

For better production and harvesting rare crops and fruits, farming system needs real time weather update. This weather monitoring system can get update of temperature, humidity, soil moisture rate, and rain detection analysis. Sometime weather climates can change unfortunately or soil needs more water or remove water, so that this device can detect this problem and give update to farmer for quick solution. This proposed system has three sensors which can detect temperature, humidity, soil moisture, and rain detection measurement from analog to digital. Raspberry Pi will receive readings from various sensors and then process the data and then data will be available on pi monitoring system for viewing of user at remote location. This system also can control soil moisture and water supply system.

Monitoring system could be design by using sensor [3] . It is useful for forecasting and data analysis process. Processing, analysis and transfer of data is very important for aspect of measurement. The main aim of this paper is to design and develop a weather monitoring system using Raspberry Pi [4] [5] . This device or monitoring system fetches weather condition like temperature humidity, soil moisture and rain detection. Knowing the exact soil moisture conditions on their fields, not only are farmers able to generally use less water to grow a crop, they are also able to increase yields and the quality of the crop by improved management of soil moisture during critical plant growth stages. Among various technology of weather forecasting system, Raspberry Pi is the latest and effective remote technology. In Raspberry Pi it uses sensor for real time weather monitoring and can get update. The system function developed using python language. This project is useful for any user who wish to monitor the current weather condition of their farm or industrial location without being physically present.


The objectives of the study are:

1) To develop an IOT based Weather Monitoring and Controlling system for a smart Agro (Farm).

2) To make an interface for maintaining and controlling the soil moisture rate of Agro farm.

3) To get the real time weather condition for a smart Agro system.

2. Literature Review

“Real Time Weather Monitoring from Remote Location Using Raspberry pi” proposed a system for Real time weather monitoring using Raspberry pi, it will measure various weather parameters like temperature, light intensity, atmospheric pressure, Gas/smoke level using appropriate sensors interfaced with Raspberry Pi, it uses wireless technology to provide real time data transfer. The project deals with designing a simple, highly efficient, cost effective and easy to operate Real time weather monitoring system. Using a database to raspberry pi this project can access from anywhere (Vijayalakshimi, K & Lakshmi, G.V, C 2016) [6] .

“Raspberry Pi Based Weather Monitoring System” proposed a system that visualize the parameters of weather variables. To know the current weather condition at remote location this system is design for. Proposed System will visualize and store various weather parameters as given above with the help of sensors interfaced to Raspberry will get all data, SD card on Pi stores the collected data as like memory card (V. Rasal, M & G. Rana, J, C 2016) [7] .

“An Intelligent Weather Station” presented an intelligent weather station for forecasting different variables of weather. To predict and analysis weather variables from anywhere. The hardware and software design of the implemented prototype are described the forecasting performance related to the three atmospheric variables, atmospheric pressure, humidity, temperature (Mestre et al. 2015).

“Weather Monitoring Using Raspberry Pi Viva Web Application” proposed an environment monitoring system. This system also capable of monitoring and control of environmental parameters like temperature, pressure and humidity. It also focused on low cost. This system uses Wireless sensor Networks for sensing the environment parameters in the area under supervision (Vasantha, J & Basha, M, 2016).

“Soil and water analysis techniques for agricultural production” proposed parameters used for the efficiency analyses in soil moisture levels. It also analysis the soil moisture level. In this paper, it discus about soil moisture, texture and average moisture value (Maral. N, 2010).

“An Effective Method for Soil Moisture Sensing using Arduino Uno and Interfacing with GSM Sim900” proposed that soil sensors are used to measure the volume fraction of water in soil. A soil moisture sensor detects the water level and provides information to accordingly control the supply of water. Also, different crops require varying amounts of water for cultivation. Here it also measures the moisture value according to the water level (Panigrahy. A et al., 2016) [8] .

“Arduino Based Automatic Plant Watering System” proposed that an artificial application of water to the land or soil. It is used to assist in the growing of agricultural crops, maintenance of landscapes, and revegetation of disturbed soils in dry areas. A high relative humidity (above 80% - 85%) should be avoided because it can increase the incidence of disease and reduce plant transpiration. In that percentage of moisture water supply must be ignored (Devika. S et al. 2014) [9] .
