241
242 (% style="color:blue" %)**GE Version**(%%): This version doesn’t include SIM card or point to any IoT server. User needs to use AT Commands to configure below two steps to set S31-NB send data to IoT server.
243
244 1. Install NB-IoT SIM card and configure APN. See instruction of [[Attach Network>>url:http://wiki.dragino.com/xwiki/bin/view/Main/General%20Configure%20to%20Connect%20to%20IoT%20server%20for%20-NB%20%26%20-NS%20NB-IoT%20models/#H2.AttachNetwork]].
245
246 1. Set up sensor to point to IoT Server. See instruction of [[Configure to Connect Different Servers>>url:http://wiki.dragino.com/xwiki/bin/view/Main/General%20Configure%20to%20Connect%20to%20IoT%20server%20for%20-NB%20%26%20-NS%20NB-IoT%20models/#H3.Configuretoconnecttodifferentservers]].

409 To save battery life, S31-NB will sample temperature & humidity data every 15 minutes and send one uplink every 2 hours. So each uplink it will include 8 stored data + 1 real-time data. They are defined by:
410
411 * (% style="color:#037691" %)**AT+TR=900**   (%%)  ~/~/  The unit is seconds, and the default is to record data once every 900 seconds (15 minutes, the minimum can be set to 180 seconds)
412
413 * (% style="color:#037691" %)**AT+NOUD=8**  (%%)~/~/   The device uploads 8 sets of recorded data by default. Up to 32 sets of record data can be uploaded.
414
415
416 The diagram below explains the relationship between TR, NOUD, and TDC more clearly:

421 == 2.5 Humidity and Temperature alarm function ==
422
423
424 On each sampling define by AT+TR ( default 900s or 15 minutes), when the value exceed the range, it will trigger an Alarm and immediately sends a uplink.
425
426
427 (% style="color:blue" %)**AT Commands:**
428
429 (% style="color:#037691" %)**AT+ SHHUM=min,max**
430
431 Example: AT+ SHHUM=50,80 ~/~/ Alarm when humidity lower than 50 or higher than 80.
432
433
434 (% style="color:#037691" %)**AT+ SHTEMP=min,max**
435
436 Example: AT+ SHTEMP=20,30 ~/~/ Alarm when temperature lower than 20 or higher than 30
437
438
439 (% style="color:red" %)**Notice:**
440
441 * To disable Alarm, user can set min and max to same value , such as (% style="color:#037691" %)**AT+SHTEMP=0,0.**
442
443 * If user only want to send only min or max, user can set the alarm to a value that device won’t reach. For example: (% style="color:#037691" %)**AT+SHTEMP=-80,0.**
