Checksum Calculation

The 8-bit CRC checksum transmitted after each data word is generated by a CRC algorithm. Its properties are

displayed in Table 18. The CRC covers the contents of the two previously transmitted data bytes. To calculate the

checksum only these two previously transmitted data bytes are used.

Conversion of Signal Output

Measurement data is always transferred as 16-bit values (unsigned integer). These values are already linearized

and compensated for temperature and supply voltage effects. Converting those raw values into a physical scale

can be achieved using the following formulas.

SRH and ST denote the raw sensor output for humidity and temperature, respectively. The formulas work only correctly

when SRH and ST are used in decimal representation.

Relative humidity conversion formula (result in %RH)：

Temperature conversion formula (result in °C )：
