Just hooked up the BMP180 board to Arduino Nano. When the serial monitor is opened I see this:
Pressure: 1025.47 hPa
Temperature: 21.30 C
Altitude: -Pressure Sensor Test
------------------------------------
Sensor: BMP085
Driver Ver: 1
Unique ID: 10085
Max Value: 300.00 hPa
Min Value: 1100.00 hPa
Resolution: 0.01 hPa
------------------------------------
Pressure: 1025.56 hPa
Temperature: 21.40 C
Altitude: -101.99 m
...etc.
I don't know what the Max and Min values are for but why is the Max less than Min?
Odd BMP180 Max Min values

Re: Odd BMP180 Max Min values
Which code are you running and what pins on the Nano are you connecting to?
