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.

386 Temperature, Humidity, Battery & Signal. This payload type only valid for ThingsSpeak Platform
387
388 As below:

393 == 2.3 Test Uplink and Change Update Interval ==
394
395
396 By default, Sensor will send uplinks (% style="color:blue" %)**every 2 hours**(%%) & AT+NOUD=8
397
398 User can use below commands to change the (% style="color:blue" %)**uplink interval**.
399
400 (% style="color:#037691" %)**AT+TDC=600 ** (%%) ~/~/ Set Update Interval to 600s
401
402 User can also push the button for more than 1 seconds to activate an uplink.
403
404
405 == 2.4 Multi-Samplings and One uplink ==
406
407
408 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:
409
410 * (% 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)
411
412 * (% 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.
413
414 The diagram below explains the relationship between TR, NOUD, and TDC more clearly:

417
418
419 == 2.5 Humidity and Temperature alarm function ==
420
421
422 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.
423
424
425 (% style="color:blue" %)**AT Commands:**
426
427 (% style="color:#037691" %)**AT+ SHHUM=min,max**
428
429 Example: AT+ SHHUM=50,80  ~/~/ Alarm when humidity lower than 50 or higher than 80.
430
431
432 (% style="color:#037691" %)**AT+ SHTEMP=min,max**
433
434 Example: AT+ SHTEMP=20,30  ~/~/ Alarm when temperature lower than 20 or higher than 30
435
436
437 (% style="color:red" %)**Notice:**
438
439 * To disable Alarm, user can set min and max to same value , such as (% style="color:#037691" %)**AT+SHTEMP=0,0.**
440
441 * 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.**
442
443 == 2.6 Trggier an uplink by external interrupt ==
444
445
446 S31-NB has an external trigger interrupt function. Users can use the PB15 pin to trigger the upload of data packets.
447
448 (% style="color:blue" %)**AT command:**
449
450 * (% style="color:#037691" %)**AT+INTMOD **(%%) ~/~/ Set the trigger interrupt mode
451
452 * (% style="color:#037691" %)**AT+INTMOD=0 **(%%) ~/~/ Disable Interrupt
453
454 * (% style="color:#037691" %)**AT+INTMOD=1 **(%%) ~/~/ Trigger by rising and falling edge
455
456 * (% style="color:#037691" %)**AT+INTMOD=2 **(%%) ~/~/ Trigger by falling edge
457
458 * (% style="color:#037691" %)**AT+INTMOD=3  **(%%) ~/~/ Trigger by rising edge
