Stage(1): A microweather station introduction

A microweather station is a small system used to measure local weather conditions such as temperature, humidity, rainfall, and wind speed in a specific area. It is uses sensors and a microcontroller to connect real-time data. This project helps in understanding local weather changes and is useful for education, agriculture, and environmental monitoring.

*) components used in project.

1. arduino uno

2. 9v battery

3. DC barrel jack

4. bread board

5. LM35 temperature sensor

16×2 LCD

SPST switch

Red green , blue LED’s

Buzzer, jumper wires , USB cables

*) Explanation / working

The microweather station works by using different sensors to measure local weather conditions like temperature, humidity, rainfall, wind speed , and air pressure. These sensors collect data and send it to microcontroller. The microcontroller processes this data and shows the readings on display or stores them for future use . In this way , the system provides real- time local weather information.
