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).

229
230
231 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.
232
233
234 Below shows the network structure:
235
236 [[image:1692415924540-357.png]]
237
238
239 There are two version: **-GE** and **-1D** version of S31-NB.
240
241
242 **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.
243
244 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]].
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]].

398
399 By default, Sensor will send uplinks **every 2 hours** & AT+NOUD=8
400
401
402 User can use below commands to change the **uplink interval**.
403
404 **~ AT+TDC=600      **~/~/ Set Update Interval to 600s
405
406
407 User can also push the button for more than 1 seconds to activate an uplink.

410
411
412 1.
413 11. Multi-Samplings and One uplink
414
415 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:
416
417 * **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)
418 * **AT+NOUD=8**  ~/~/   The device uploads 8 sets of recorded data by default. Up to 32 sets of record data can be uploaded.

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

468
469 S31x-LB supports below configure method:
470
471 * AT Command via Bluetooth Connection (**Recommended**): [[BLE Configure Instruction>>http://wiki.dragino.com/xwiki/bin/view/Main/BLE%20Bluetooth%20Remote%20Configure/]].
472 * AT Command via UART Connection : See [[UART Connection>>http://wiki.dragino.com/xwiki/bin/view/Main/UART%20Access%20for%20LoRa%20ST%20v4%20base%20model/#H2.3UARTConnectionforSN50v3basemotherboard]].
