Odd BMP180 Max Min values

Post by philg »

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?

Which code are you running and what pins on the Nano are you connecting to?
