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).

227
228
229 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 (% 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.
241
242 * 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]].

383 == 2.3 Test Uplink and Change Update Interval ==
384
385
386 By default, Sensor will send uplinks (% style="color:blue" %)**every 2 hours**(%%) & AT+NOUD=8
387
388 User can use below commands to change the (% style="color:blue" %)**uplink interval**.
389
390 (% style="color:#037691" %)**AT+TDC=600 ** (%%) ~/~/ Set Update Interval to 600s
391
392 User can also push the button for more than 1 seconds to activate an uplink.
393
394
395 == 2.4 Multi-Samplings and One uplink ==
396
397
398 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:
399
400 * (% 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)
401
402 * (% 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.
403
404 The diagram below explains the relationship between TR, NOUD, and TDC more clearly:

408
409 == 2.5 Humidity and Temperature alarm function ==
410
411
412 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.
413
414
415 (% style="color:blue" %)**AT Commands:**
416
417 (% style="color:#037691" %)**AT+ SHHUM=min,max**
418
419 Example: AT+ SHHUM=50,80  ~/~/ Alarm when humidity lower than 50 or higher than 80.
420
421
422 (% style="color:#037691" %)**AT+ SHTEMP=min,max**
423
424 Example: AT+ SHTEMP=20,30  ~/~/ Alarm when temperature lower than 20 or higher than 30
425
426
427 (% style="color:red" %)**Notice:**
428
429 * To disable Alarm, user can set min and max to same value , such as (% style="color:#037691" %)**AT+SHTEMP=0,0.**
430
431 * 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.**
432
433 == 2.6 Trggier an uplink by external interrupt ==
434
435
436 S31-NB has an external trigger interrupt function. Users can use the PB15 pin to trigger the upload of data packets.
437
438 (% style="color:blue" %)**AT command:**
439
440 * (% style="color:#037691" %)**AT+INTMOD **(%%) ~/~/ Set the trigger interrupt mode
441
442 * (% style="color:#037691" %)**AT+INTMOD=0 **(%%) ~/~/ Disable Interrupt
443
444 * (% style="color:#037691" %)**AT+INTMOD=1 **(%%) ~/~/ Trigger by rising and falling edge
445
446 * (% style="color:#037691" %)**AT+INTMOD=2 **(%%) ~/~/ Trigger by falling edge
447
448 * (% style="color:#037691" %)**AT+INTMOD=3  **(%%) ~/~/ Trigger by rising edge
