Our project aims is to detect the current weather using the Windows Phone's Light Sensor combine to the current time.

To gather data from the Light Sensor, we use the LightSensor class from the Windows.Devices.Sensors namespace, which is available since Windows Phone 8.1 SDK is up. This class returns the ambient-light reading as a LUX value. To get the current time, we also use the DateTime class from the System namespace. For our detection we round the current time to the below hour.

To get the weather from these values, we use a neural network. To create this neural network with use the alglib library . We trained this neural network with several values which respect these hypothesis :

• dark indoor : 0-50 lux, from 7am to 6pm
• very cloudy : 51-5000 lux, from 7am to 6pm
• sunny with some cloud : 5001-30000 lux, from 7am to 6pm
• sunset : 10001-30000 lux, at 6pm
• sunny without cloud : 30001-100000 lux, from 7am to 6pm
• moonless night : 0-10 lux, from 7pm to 6am
• fullmoon night : 11-50 lux, from 7pm to 6am
• home light : 51-100000 lux, from 7pm to 6am
• sunrise : 10001-30000 lux, at 6am

Once the neural network is trained, we can determine the weather using this network, the current lux value and the current time.
