 Consider the BMP180 sensor (I'm not certain if "discontinued" applies
just to AdaFruit's board, or the sensor itself:
https://www.adafruit.com/product/1603 ).

"""
Pressure sensing range: 300-1100 hPa (9000m to -500m above sea level)
Up to 0.03hPa / 0.25m resolution
-40 to +85°C operational range, +-2°C temperature accuracy
