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.
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.
The sensors used in this kit are:
ST LPS22HB which measures atmospheric pressure.
ST HTS221 which measures temperature and humidity, and
VISHAY TEMT6000 which measures Lux of the ambient light.
