Upgrade your microcontroller or single board computer and reliably measure air pressure! Barometers are generally used in meteorology and are part of the absolute standard equipment of every weather station. They are also used to measure altitude, as air pressure decreases with increasing altitude. In our online shop for electronic components, you will find a large selection of suitable sensors that can be connected to your Raspberry Pi or Arduino Uno, for example. We rely on the high quality of manufacturers such as BlueDot, Sparkfun and Adafruit when it comes to air pressure measurement.
