Windows IoT Weather Station Project
Build Your Own Smart Weather Station
This project guides you through building a comprehensive weather station using Windows IoT Core. Monitor temperature, humidity, pressure, and more, directly from your device. Learn how to interface with sensors, collect data, and visualize it in real-time.
Perfect for hobbyists, educators, and developers looking to explore the capabilities of Windows IoT for environmental monitoring.

Project Goals
Develop a functional IoT device.
Understand sensor integration and data acquisition.
Gain experience with Windows IoT development.
Create a platform for environmental data analysis.
Getting Started
Follow these steps to set up your own weather station.
1. Setup Windows IoT
Install Windows IoT Core on your compatible device. Refer to the official Microsoft documentation for detailed instructions.
2. Connect Sensors
Wire your chosen sensors to the GPIO pins of your IoT device. Ensure proper voltage and connection configurations.
3. Develop Application
Write your application code using C#. Utilize provided code samples and sensor libraries to read data.
4. Deploy and Run
Deploy your application to the Windows IoT device and start collecting environmental data.
Code Snippet Example
A basic example of reading from a DHT sensor.

using System.Threading.Tasks;
using Windows.Devices.Gpio;
using Windows.Devices.Sensors;
public sealed class WeatherSensor
{
private TemperatureAndHumiditySensor _dhtSensor;

{
// Replace with your sensor's controller and pin number
var controller = await GpioController.GetDefaultAsync();
// Assuming DHT22 on pin 4
var pin = controller.OpenPin(4);
// Initialize the sensor (may vary based on specific DHT sensor library)
// Example: _dhtSensor = new TemperatureAndHumiditySensor(pin);
// For demonstration, we'll use a simplified approach or placeholder
Console.WriteLine("Sensor initialized. Placeholder for DHT sensor.");
// Simulate getting readings
_dhtSensor = TemperatureAndHumiditySensor.GetDefault();

// Example usage in your main application logic:
/*
var weatherStation = new WeatherSensor();
await weatherStation.InitializeAsync();
// Later, in a loop or event handler:
var readings = await weatherStation.GetCurrentReadingsAsync();
