Command

Hex code

Fetch Data

0x E0 00

Table 10: Fetch Data command (Clear blocks are

controlled by the microcontroller, grey blocks by the

sensor).

4.8 ART Command

The ART (accelerated response time) feature can be activated by issuing the command in Table 11. After issuing the

ART command the sensor will start acquiring data with a frequency of 4Hz.

The ART command is structurally similar to any other command in Table 9. Hence Section 4.6 applies for starting a

measurement, Section 4.7 for reading out data and Section 4.9 for stopping the periodic data acquisition.

ART feature (Clear blocks are controlled by the

microcontroller, grey blocks by the sensor).

4.9 Break command / Stop Periodic Data Acquisition Mode

The periodic data acquisition mode can be stopped using the break command shown in Table 12. It is recommended to

stop the periodic data acquisition prior to sending another command (except Fetch Data command) using the break

command. Upon reception of the break command the sensor will abort the ongoing measurement and enter the single

shot mode. This takes 1ms.
