23
24
25 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*.
26
27 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.
28
29 S31-NB supports different uplink methods include (% style="color:blue" %)**TCP, MQTT, UDP**(%%) for different application requirement. and Support Uplinks to various IoT Servers.
30
31 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).

403
404
405 By default, Sensor will send uplinks (% style="color:blue" %)**every 2 hours**(%%) & AT+NOUD=8
406
407 User can use below commands to change the (% style="color:blue" %)**uplink interval**.
408
409 (% style="color:#037691" %)**AT+TDC=600 ** (%%) ~/~/ Set Update Interval to 600s
410
411 User can also push the button for more than 1 seconds to activate an uplink.
412
413
414 == 2.4 Multi-Samplings and One uplink ==
415
416 (% style="color:red" %)Notice: The AT+NOUD feature is upgraded to Clock Logging, please refer [[Clock Logging Feature>>||anchor="H2.7Clocklogging28Sincefirmwareversionv1.2.129"]]
417
418 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:
419
420 * (% 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)
421
422 * (% 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.
423
424 The diagram below explains the relationship between TR, NOUD, and TDC more clearly:

429 == 2.5 Humidity and Temperature alarm function ==
430
431
432 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.
433
434
435 (% style="color:blue" %)**AT Commands:**
436
437 (% style="color:#037691" %)**AT+ SHHUM=min,max**
438
439 Example: AT+ SHHUM=50,80  ~/~/ Alarm when humidity lower than 50 or higher than 80.
440
441
442 (% style="color:#037691" %)**AT+ SHTEMP=min,max**
443
444 Example: AT+ SHTEMP=20,30  ~/~/ Alarm when temperature lower than 20 or higher than 30
445
446
447 (% style="color:red" %)**Notice:**
448
449 * To disable Alarm, user can set min and max to same value , such as (% style="color:#037691" %)**AT+SHTEMP=0,0.**
450
451 * 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.**
452
453 == 2.6 Trggier an uplink by external interrupt ==
454
455
456 S31-NB has an external trigger interrupt function. Users can use the PB15 pin to trigger the upload of data packets.
457
458 (% style="color:blue" %)**AT command:**
459
460 * (% style="color:#037691" %)**AT+INTMOD **(%%) ~/~/ Set the trigger interrupt mode

467
468 * (% style="color:#037691" %)**AT+INTMOD=3  **(%%) ~/~/ Trigger by rising edge
469
470 == 2.7 Clock logging (Since firmware version v1.2.1) ==
471
472
473 Sometimes when we deploy lots of end nodes in field. We want all sensors sample data at the same time, and upload these data together for analyze. In such case, we can use clock loging feature.
474
475 We can use this command to set the start time of data recording and the time interval to meet the requirements of the specific collection time of data.
476
477 * (% style="color:blue" %)**AT command:**(%%)** (% style="color:#037691" %)AT+CLOCKLOG=a,b,c,d(%%)**

488
489 **Example:**
490
491 **AT+CLOCKLOG=1,65535,1,5**
492
493 After the node sends the first packet, data is recorded to the memory at intervals of 1 minute. For each TDC uplink, the uplink load will include: battery information + the last 5 memory records (payload + timestamp).
