5. Data Report
The device will immediately send a version packet report and a data report including voltage of the battery and TVOC value.
The device sends data according to the default configuration before any other configuring.
Default Setting:
Maximum time: Max Interval
=
15 min
Minimum time: Min Interval =
15 min
*
Minimum time should not be less than 4min.
Battery Change
=
0x01 (0.1V)
TVOC Change = 0x012C (300 ppb)
TVOC Measurement Range
:
0 ppb to 60000 ppb
Excellent
0 to 65 ppb
Good
65 to 220 ppb
Moderate
220 to 660 ppb
Poor
660 to 2200 ppb
Unhealthy
2200 to 60000 ppb
Note:
1.
R720E needs to
work for 13 hours after the first power-on
.
(The sensor needs to be calibrated automatically during the 13 hours, and the data will be biased during this period. The
accurate data shall prevail after 13 hours. At present, this step has been completed before the shipment.)
2.
On the condition that the sensor can operate normally, the read data is valid after the device is powered off and has
been turned on again for
20 minutes
.
(The 20 minutes is the time for the sensor to enter a stable state.)
3.
The device will report
0xFFFF
when the sensor is damaged, the initiation fails, and the device fails to read the data
three times continuously after warming up.
*The above process will be completed automatically after the device is turned on; therefore, users do not need to
operate by self.
