AT+SHTEMP=0,30 // Alarm when temperature higher than 30.
➢ Downlink Payload:
0x(0C 01 00 1E): //Set AT+SHTEMP=0,30
(note: 3
rd
byte= 0x00 for low limit(not set), 4
th
byte = 0x1E for high limit: 30)
Set Humidity Alarm Threshold:
➢ AT Command:
AT+SHHUM=min,max
When min=0, and max≠0, Alarm higher than max
When min≠0, and max=0, Alarm lower than min
When min≠0 and max≠0, Alarm higher than max or lower than min
Example:
AT+SHHUM=70,0 // Alarm when humidity lower than 70%.
➢ Downlink Payload:
0x(0C 02 46 00): //Set AT+SHTHUM=70,0
(note: 3

Set Alarm Interval:
The shortest time of two Alarm packet. (unit: min)
➢ AT Command:
AT+ATDC=30 // The shortest interval of two Alarm packets is 30 minutes, Means is there is an
alarm packet uplink, there won’t be another one in the next 30 minutes.
➢ Downlink Payload:
0x(0D 00 1E) ---> Set AT+ATDC=0x 00 1E = 30 minutes
