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]].

412 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:
413
414 * (% 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)
415
416 * (% 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.
417
418
419 The diagram below explains the relationship between TR, NOUD, and TDC more clearly:

424 == 2.5 Humidity and Temperature alarm function ==
425
426
427 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.
428
429
430 (% style="color:blue" %)**AT Commands:**
431
432 (% style="color:#037691" %)**AT+ SHHUM=min,max**
433
434 Example: AT+ SHHUM=50,80 ~/~/ Alarm when humidity lower than 50 or higher than 80.
435
436
437 (% style="color:#037691" %)**AT+ SHTEMP=min,max**
438
439 Example: AT+ SHTEMP=20,30 ~/~/ Alarm when temperature lower than 20 or higher than 30
440
441
442 (% style="color:red" %)**Notice:**
443
444 * To disable Alarm, user can set min and max to same value , such as (% style="color:#037691" %)**AT+SHTEMP=0,0.**
445
446 * 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.**
