20 The Dragino S31-NB and S31B-NB are (% style="color:blue" %)**NB-IoT Temperature and Humidity Sensor**(%%) for Internet of Things solution. It is used to measure the surrounding (% style="color:blue" %)**environment temperature and relative air humidity precisely**(%%), and then upload to IoT server via NB-IoT network*.
21
22 The temperature & humidity sensor used in S31-NB is SHT31, which is fully calibrated, linearized, and temperature compensated digital output from Sensirion, it provides a strong reliability and long-term stability. The SHT31 is fixed in a (% style="color:blue" %)**waterproof anti-condensation casing**(%%) for long term use.
23
24 S31-NB supports different uplink methods include (% style="color:blue" %)**TCP, MQTT, UDP** for different application requirement. and Support Uplinks to various IoT Servers.
25
26 S31-NB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), It is designed for long term use up to several years. (Real-world battery life depends on the use environment, update period and uplink method. Please check related Power Analyze report).

228
229
230 The S31-NB is equipped with a NB-IoT module, the pre-loaded firmware in S31-NB will get environment data from sensors and send the value to local NB-IoT network via the NB-IoT module.  The NB-IoT network will forward this value to IoT server via the protocol defined by S31-NB.

240
241 (% 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.
242
243 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]].
244
245 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]].

394
395
396 By default, Sensor will send uplinks (% style="color:blue" %)**every 2 hours**(%%) & AT+NOUD=8
397
398
399 User can use below commands to change the (% style="color:blue" %)**uplink interval**.
400
401 (% style="color:#037691" %)** AT+TDC=600      ** (%%) ~/~/ Set Update Interval to 600s
402
403
404 User can also push the button for more than 1 seconds to activate an uplink.
405
406
407
408
409 == 2.4 Multi-Samplings and One uplink ==
410
411
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 The diagram below explains the relationship between TR, NOUD, and TDC more clearly:

423 == 2.5 Humidity and Temperature alarm function ==
424
425
426 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.
427
428
429 (% style="color:blue" %)**AT Commands:**
430
431 (% style="color:#037691" %)**AT+ SHHUM=min,max**

437
438 Example: AT+ SHTEMP=20,30 ~/~/ Alarm when temperature lower than 20 or higher than 30
439
440
441 (% style="color:red" %)**Notice:**
442
443 * To disable Alarm, user can set min and max to same value , such as (% style="color:#037691" %)**AT+SHTEMP=0,0.**
444
445 * 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.**
