The click can measure temperature as well, it has a 16-bit temperature data output.

LPS22HB click works on a 3.3V power supply only.

Barometer facts

As you probably already know, barometers measure atmospheric pressure. But did you know that the idea of air having any sort of weight was not considered seriously, until the late Renaissance times?

Italian scientists Evangelista Torricelli invented the barometer around 1640. For his measurements, he used mercury, due to the fact that it is about 14 times denser that water.
