These sensors are of the latest generation and measure:

• Atmospheric pressure
• Temperature and humidity
• Light intensity (in LUX, max 650)

To help you build projects and store the data collected locally, this shield has a slot for a microSD card (not provided).

There is a ready to use library with examples and methods to read values from the different sensors, that provides an easy and smooth integration path.

Sensors used :  

• ST  :  atmospheric pressure 
• ST   : temperature and humidity
• VISHAY  : Lux of the ambient.
