++Case 1:Door Sensor. 3.3v Out for such sensor is just to detect Open/Close.
++
++ In Open State, the power consumption is the same as if there is no probe
++
++ In Close state, the power consumption will be 3uA higher than normal.

++Parameter 1: Alarm mode:

++0): Cancel

++1): Threshold alarm
++
++2): Fluctuation alarm
++
++
++Parameter 2: Sampling time. Unit: seconds, up to 255 seconds.
++
++**Note: When the collection time is less than 60 seconds and always exceeds the set alarm threshold, the sending interval will not be the collection time, but will be sent every 60 seconds.**
++
++
++Parameter 3 and parameter 4:
++
++1):If Alarm Mode is set to 1: Parameter 3 and parameter 4 are valid, as before, they represent low temperature and high temperature.
++
++Such as AT+WMOD=1,60,45,105, it means high and low temperature alarm.
++
++
++2):If Alarm Mode is set to 2: Parameter 3 is valid, which represents the difference between the currently collected temperature and the last uploaded temperature.
++
++Such as AT+WMOD=2,10,2,it means that it is a fluctuation alarm.
++
++If the difference between the current collected temperature and the last Uplin is ±2 degrees, the alarm will be issued.
