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).

225
226
227 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.

391 == 2.3 Test Uplink and Change Update Interval ==
392
393
394 By default, Sensor will send uplinks (% style="color:blue" %)**every 2 hours**(%%) & AT+NOUD=8
395
396 User can use below commands to change the (% style="color:blue" %)**uplink interval**.
397
398 (% style="color:#037691" %)**AT+TDC=600 ** (%%) ~/~/ Set Update Interval to 600s
399
400 User can also push the button for more than 1 seconds to activate an uplink.
401
402
403 == 2.4 Multi-Samplings and One uplink ==
404
405
406 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:
407
408 * (% 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)
409
410 * (% 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.
411
412 The diagram below explains the relationship between TR, NOUD, and TDC more clearly:

415
416
417 == 2.5 Humidity and Temperature alarm function ==
418
419
420 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.
421
422
423 (% style="color:blue" %)**AT Commands:**
424
425 (% style="color:#037691" %)**AT+ SHHUM=min,max**
426
427 Example: AT+ SHHUM=50,80  ~/~/ Alarm when humidity lower than 50 or higher than 80.
428
429
430 (% style="color:#037691" %)**AT+ SHTEMP=min,max**
431
432 Example: AT+ SHTEMP=20,30  ~/~/ Alarm when temperature lower than 20 or higher than 30
433
434
435 (% style="color:red" %)**Notice:**
436
437 * To disable Alarm, user can set min and max to same value , such as (% style="color:#037691" %)**AT+SHTEMP=0,0.**
438
439 * 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.**
440
441 == 2.6 Trggier an uplink by external interrupt ==
442
443
444 S31-NB has an external trigger interrupt function. Users can use the PB15 pin to trigger the upload of data packets.
445
446 (% style="color:blue" %)**AT command:**
447
448 * (% style="color:#037691" %)**AT+INTMOD **(%%) ~/~/ Set the trigger interrupt mode
449
450 * (% style="color:#037691" %)**AT+INTMOD=0 **(%%) ~/~/ Disable Interrupt
451
452 * (% style="color:#037691" %)**AT+INTMOD=1 **(%%) ~/~/ Trigger by rising and falling edge
453
454 * (% style="color:#037691" %)**AT+INTMOD=2 **(%%) ~/~/ Trigger by falling edge
455
456 * (% style="color:#037691" %)**AT+INTMOD=3  **(%%) ~/~/ Trigger by rising edge
