3.4 Calibration coefficients
The 176 bit E
coefficients. Every sensor module has individual coefficients. Before the first calculation of
temperature and pressure, the master reads out the E
The data communication can be checked by checking that none of the words has the value 0 or
0xFFFF.
3.5 Calculating pressure and temperature
The mode (ultra low power, standard, high, ultra high resolution) can be selected by the variable
oversampling_setting (0, 1, 2, 3) in the C code.
The universal code SMD500/BMP085 is fully upward compatible to SMD500 and recognizes
automatically the device ID. Thus, the SMD500 can be replaced "on the fly" by the BMP085
without changing hardware or software.
Calculation of true temperature and pressure in steps of 1Pa (= 0.01hPa = 0.01mbar) and
temperature in steps of 0.1°C.
