This project features an IoT Weather Station using the Arduino Uno R4 Wi-Fi. It monitors temperature, humidity, atmospheric pressure, wind speed, wind direction, and rainfall using various sensors. Data is uploaded in real-time to the Blynk app for easy remote access and monitoring, making it a versatile tool for weather tracking.
IMPACT STATEMENT
1.Increased Accessibility: With user-friendly apps like Blynk, anyone can easily access weather data. This helps people make better decisions about farming, outdoor events, and safety during storms. 2.Cost-Effective: Using affordable components like sensors and Arduino boards keeps the project within a low budget. This makes it possible for schools and small communities to set up their own weather stations without spending too much. 3.Customizable and Scalable: The system can be easily adjusted to fit different needs. Users can add more sensors or change settings based on their specific requirements. It can also grow over time as more features are added. 4.Remote Access: With WiFi capabilities, users can check weather data from anywhere. This is particularly useful for farmers and emergency responders who need up-to- date information to make important decisions. 5.Research and Education: This project provides a hands-on learning experience for students. It encourages interest in science and technology by allowing them to explore how weather works and how to use technology to measure it.
OVERVIEW
