IoT Weather Monitoring System Architecture

Introduction

The system utilizes sensors to gather real-time data on various atmospheric conditions, including temperature, humidity, wind speed, precipitation, and rainfall. These systems are crucial in various sectors like disaster management, transportation, and agriculture.

The weather data can be accessed from anywhere using mobile and web apps, enabling proactive decision-making in response to changing weather patterns.

Weather Monitoring System Components

Like any other IoT system, it consists of sensors, a Microcontroller Unit (MCU) or Microprocessor Unit (MPU) including a wireless module, a power supply, and cloud connectivity.

Sensors are installed at different locations to gather weather related data, as described below. The MCU or MPU collects data from sensors and uploads it to cloud servers such as AWS, Azure, ThinkSpeak, and Google. The power supply is needed to power the MCU/MPU. Cloud connectivity can be established using WiFi or cellular connections.
