This project\'s suggested system is a cutting-edge method of keeping an eye on the local weather and disseminating the data anywhere in the globe. This is made possible by Internet of Things (IoT) technology, which is a sophisticated and effective way to link objects to the internet and to link everything in the world together in a network. Anywhere in the world can access the updated data from the established system over the internet. During some weather dangers, it will be extremely difficult to examine and monitor the weather parameters in the agriculture zone using cables and analog instruments. Here, wireless sensors are utilized to examine and monitor the meteorological data in order to solve this issue.

Introduction

I. INTRODUCTION

Here we provide an intelligent online weather reporting system. We have implemented a system that enables online reporting of weather parameters. It eliminates the need for weather forecasting services by enabling individuals to examine the current weather conditions immediately online. The system tracks temperature, humidity, and precipitation along with a humidity sensor to offer real-time weather statistics reporting. Using a temperature sensor, the system continuously checks the temperature, the humidity, and the presence of rain. The task of a weather monitoring system is to identify and collect a variety of meteorological parameters at multiple sites so that they can be analyzed or utilized for weather forecasting.

II. RELATED WORK

The Internet of Things (IoT) is a major factor in wireless weather stations, since it facilitates real-time weather reporting, data collecting, analysis, and remote monitoring. This article examines the literature on weather stations in detail. This project assists in the detection of various weather conditions and provides warnings to all users via an LED, a buzzer, and an SMS to a registered cellphone number. It measures the temperature, humidity, and quality of the air in the atmosphere. By detecting the brightness of the light, it also finds the fire. Weather forecasting is essential to agriculture because it helps farmers make decisions and manage their crops in a variety of ways. Precise predictions assist farmers in organizing their planting and harvesting timetables, optimizing irrigation techniques, and proficiently handling pest and disease outbreaks. By Farmers can reduce their exposure to extreme weather events like storms, floods, and droughts, which can have a major negative influence on crop yields and farm profitability, by forecasting weather trends. Furthermore, weather forecasts help to minimize costs and environmental effect by allocating resources like water, fertilizer, and pesticides in an efficient manner. In summary, weather forecasting gives farmers the opportunity to make well-informed decisions, increase output, and guarantee the sustainability of their businesses in the face of shifting weather patterns. Unfavorable weather conditions frequently cause farmers to suffer large losses, which can have a catastrophic impact on agricultural productivity and financial stability. Droughts, floods, frost, hailstorms, and heatwaves are examples of unpredictable weather patterns that can harm crops, lower yields, or even wipe out entire harvests. Overabundance of rain can cause soil erosion or flooding, which can harm crop quality and growth. On the other hand, extended dry spells can dehydrate the soil, which will impede plant development and reduce harvests. Abnormally high or low temperatures can also have a detrimental effect on crop growth and reduce yields. In addition, erratic weather patterns have the potential to interfere with planting and harvesting plans, resulting in less marketable food and financial losses for farmers. All things considered, farmers face a great deal of unpredictability due to weather patterns, which emphasizes the importance of resilient farming methods and efficient risk management techniques.

Weather forecasting is essential for fire stations because it enables personnel to anticipate and get ready for any fire threats. Precise predictions offer significant understanding of variables including temperature, humidity, wind direction, and precipitation, all of which have a direct impact on the behavior of fires and their ability to spread. In order to efficiently respond to fire occurrences, fire stations can alter staffing levels, proactively deploy resources, and apply strategic firefighting tactics by keeping an eye on weather forecasts. Furthermore, weather forecasts help fire departments alert the public in a timely manner about fire danger levels and recommend fire safety precautions. In general, weather forecasting is essential for improving fire stations' readiness and response times, which in turn helps to reduce the hazards associated with wildfires and save lives and property. By sending out alerts, this project hopes to assist both fire stations and farmers in preventing damage caused by unsuitable weather.
