the threshold. Note that when you change the temperature unit, please re-configure the
threshold.
For CO2, TVOC, PM2.5, PM10 and HCHO, it supports defining Excellent, Polluted and Bad
threshold for traffic light, buzzer and screen alarms. Besides, when one of concentrations of air
pollutants exceeds the Bad threshold, LEO-S592-AQG0 will upload the current data once
instantly.

19
4.5.5 Data Retransmission
LEO-S592-AQG0 sensor supports data retransmission to ensure network server can get all data
even if network is down for some times. There are two ways to get the lost data:
⚫Network server sends downlink commands to enquire the historical data for specifying time
range, see section 6.4;
⚫When network is down if no response from LinkCheckReq MAC packets for a period of time,
the device will record the network disconnected time and re-transmit the lost data after
device re-connects the network.
Here are the steps for data retransmission:
1. Ensure the device time is correct (see section 4.3);
2. Enable data storage feature and data retransmission feature;
3. Enable rejoin mode feature and set the number of packets sent. Take below as example, the
device will send LinkCheckReq MAC packets to the network server at least every 30 mins to

www.advantech.com
20
check if the network is disconnected; if there is no response for 8 times (8 * 30 mins = 240 mins
=4 hours), the device will record a data lost time point( disconnection time minus 4 hours).
4. After the network connected back, the device will send the lost data from the point in time when
the data was lost according to the reporting interval.
Note:
1) If the device is rebooted or re-powered when data retransmission is not completed, the device
will re-send all retransmission data again after device is reconnected to the network;
2) If the network is disconnected again during data retransmission, it will only send the latest
disconnection data;
3) The retransmission data format is started with “20ce”, please refer to see section 6.4.
