I just received the MS5037 and connected it to an Arduino Uno with a SparkFun Logic Level controller. And while it does communicate with the Arduino and does report the correct value for Temperature, the pressure, depth, and altitude values are all off. I’m not sure what to do to fix this issue.
Serial Monitor:
Pressure: 20149.00 mbar
Temperature: 24.90 deg C
Depth: 195.72 m
Altitude: -33957.73 m above mean sea level
code:
I’ve been using the code provided in the library’s example.
I’m running into an interesting problem when I connect both Bar02 sensors to a multiplexer. I have 1 that’s reading fine but the other gives readings a higher than the other. The sensors read the following:
Pressure 1: 1182.00 mbar
Temperature 1: 32.15 deg C
Depth 1: 1.73 m
Altitude 1: -1317.98 m above mean sea level
Pressure 2: 1003.00 mbar
Temperature 2: 25.29 deg C
Depth 2: -0.10 m
Altitude 2: 85.64 m above mean sea level
The first pressure sensor always reads within those values even if I connect it directly to the Arduino Board. So I would guess something is off. What’s really weird is that if I move the depth equation from the library to the code both sensors read equally with negligible variation.
Pressure 1: 1182.00 mbar
Temperature 1: 32.17 deg C
Depth 1 Lib: 1.73 m
Depth 1 Calc: -10.24 m
Altitude 1: -1317.98 m above mean sea level
Pressure 2: 1003.00 mbar
Temperature 2: 25.49 deg C
Depth 2 Lib: -0.10 m
Depth 2 Calc: -10.26 m
Altitude 2: 85.64 m above mean sea level
