PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
The latest measurement acquisition in Auto Measurement Mode can be retrieved using measurement readout commands, which are documented in Table 7-4, and illustrated in Figure 7-12. Once the measurement readout is complete, the HDC302x-Q1 clears the measurement result. Therefore, if the next attempt to read data occurs before the following conversion attempt, the read results are +130°C for temperature and +100%RH for humidity.
As in Trigger-On Demand, if the I2C controller attempts to read the measurement results prior to measurement completion, the HDC302x-Q1 responds with a NACK condition.
