Reading the HS310x ID Number

The sensor ID is a 32-bit number, and can be read in a similar fashion as illustrated in steps 1 and 2 of

Figure 18, using the appropriate register address values. The ID number is stored in two registers, with the

upper and lower 16 bits stored in register addresses 0x1E and 0x1F, respectively.

Calculating Humidity and Temperature Output

The entire output of the HS310x is 4 bytes. The relative humidity (in percent) and the temperature (in degrees

Celsius) are calculated using Equation 1 and Equation 2, respectively.
