374 -If payload & 0x01 = 0x01  **~-~->** This is an Alarm Message.It means that the temperature and humidity exceed the alarm value or trigger an interrupt.
382 +If payload is 0x64 = 100%
375 375  
376 -If payload & 0x01 = 0x00  **~-~->** This is a normal uplink message, no alarm.

389 +If payload is 0x46 = 70%
383 383  
384 -If payload >> 2 = 0x31  **~-~->**  means MOD=31, this message is a reply message for polling, this message contains the alarm settings. see [[this link>>path:#HPolltheAlarmsettings:]] for detail.

394 +Because the food temperature data is a little-endian sequence, the order of the front and back bytes needs to be swapped during decoding.

391 -If payload is: 0105H:  (0105 & 8000 == 0), temp = 0105H /10 = 26.1 degree
