IoT based weather monitoring system architecture

The system employs sensors to collect real time data on various atmospheric conditions such as temperature, humidity, wind speed, precipitation, rain etc. These systems play crucial role in various sectors which include disaster management, transportation, agriculture etc. The weather data can be checked from anywhere using mobile and web apps which helps in taking proactive decisions in response to change in weather patterns.

Weather Monitoring System

Like any other IoT system, it consists of sensors, MCU (Microcontroller Unit) or MPU (Microprocessor Unit) including wireless module, power supply and cloud connectivity. Sensors are installed at different locations as required for gathering weather related data as described below. MCU or MPU collects data from sensors and uploads them to cloud servers such as AWS, Azure, ThinkSpeak, Google etc. Power supply is needed to power the MCU/MPU. Cloud connectivity can be done using wifi or cellular connections.
