Exact determination of altitude by measuring pressure is needed in many applications. I compare three generations of pressure sensors, the BMP085, the BMP180 and the BME280 from Bosch and find out, how exact they measure.
I use an Arduino Due and a Maple Mini to calculate the results and export them into Excel for analysis.
