3.1.2. Performing a Temperature Measurement

The following steps should be performed in sequence to take a temperature measurement:

6. Set START (D0) and TEMP (D4) in CONFIG (register 0x03) to begin a new conversion, i.e., write CONFIG with

0x11

7. Poll RDY (D0) in STATUS (register 0) until it is low (=0)

8. Read the upper and lower bytes of the temperature value from DATAh and DATAl (registers 0x01 and 0x02),

respectively

Table 12 shows the format of the 14-bit temperature result. This value may be converted to °C using the following

equation:

where TEMP is the measured value returned in DATAh:DATAI.

Table 13shows the 14-bit values that correspond to various measured temperature levels.
