Arduino Library for the BARO barometric pressure module

barosensor's Issues

Type error causing problems below 20DegC

Hay think I found it, line 107, BaroSensor.cpp
int64_t dt = d2 - c5 * (1L<<8);

should read

int32_t dt = d2 - c5 * (1L<<8);

Doing this solved my Less than 20DegC issue.

No Reliable reading Below 20DegC

While testing the Baro sensor I noticed that readings for the Temp And Baro were very inaccurate.
Blowing across the sensor to increase the temp readings returned to an expected value.
Taking note of the temp as it fell from 20.10DegC to Less than 20DegC I noticed that there was a limit at which the sensor would give correct values which was above 20DegC.

Page 7 of the datasheet provided by freetronics showed why.
Sorry Just saw second order compensation on the git page.
