Sensor Configuration

ATINTTIME=

<value>

Set integration time for all devices AS72651, AS72652, AS72653.

Value should be in the range [1...255], with

integration time = <value> * 2.8ms. (default value = 255)

ATINTTIME

<value> OK

Read sensor integration time (same for all devices)

integration time = <value> * 2.8ms.

ATGAIN=

<value>

Set gain for all devices AS72651, AS72652, AS72653:

0=1x, 1=3.7x, 2=16x, 3=64x

(default value = 0)

ATGAIN

<value>OK

Read all gain setting for all devices, returning 0, 1, 2, or 3 as defined

immediately above.

ATTEMP

<value3>OK

Read internal temperature in the order of AS72651, AS72652,

AS72653 in celsius

ATTCSMD=

<value>

Set Sensor Mode

0 = BANK Mode 0;

1 = BANK Mode 1;

2 = BANK Mode 2;

(default value = 2)

ATTCSMD

<value> OK

Read Sensor Mode, see above
