150

151

152

The SN50v3-LB is configured as (% style="color:#037691" %)**LoRaWAN OTAA Class A**(%%) mode by default. It has OTAA keys to join LoRaWAN network. To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and press the button to activate the S31x-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

Following is an example for how to join the [[TTN v3 LoRaWAN Network>>url:https://console.cloud.thethings.network/]]. Below is the network structure; we use the [[LPS8v2>>url:https://www.dragino.com/products/lora-lorawan-gateway/item/228-lps8v2.html]] as a LoRaWAN gateway in this example.

159

160

The LPS8V2 is already set to connected to [[TTN network >>url:https://console.cloud.thethings.network/]], so what we need to now is configure the TTN server.

276

277

278

SN50v3 has different working mode for the connections of different type of sensors. This section describes these modes. Use can use the AT Command AT+MOD to set SN50v3 to different working modes.

For example:

**AT+MOD=2 ** ~/~/ will set the SN50v3 to work in MOD=2 distance mode which target to measure distance via Ultrasonic Sensor.

283

285

(% style="color:red" %) **Important Notice:**

286

287

1. Some working modes has payload more than 12 bytes, The US915/AU915/AS923 frequency bands' definition has maximum 11 bytes in **DR0**. Server sides will see NULL payload while SN50v3 transmit in DR0 with 12 bytes payload.

Each HX711 need to be calibrated before used. User need to do below two steps:

418

419

1. Zero calibration. Don't put anything on load cell and run **AT+WEIGRE** to calibrate to Zero gram.

420

1. Adjust calibration factor (default value 400): Put a known weight thing on load cell and run **AT+WEIGAP** to adjust the Calibration Factor.

421

1. (((

422

Weight has 4 bytes, the unit is g.

)))

For example:

**AT+GETSENSORVALUE =0**

428

429

Response: Weight is 401 g

458

In this mode, the device will work in counting mode. It counts the interrupt on the interrupt pins and sends the count on TDC time.

459

460

Connection is as below. The PIR sensor is a count sensor, it will generate interrupt when people come close or go away. User can replace the PIR sensor with other counting sensors.

**Note:** LoRaWAN wireless transmission will infect the PIR sensor. Which cause the counting value increase +1 for every uplink. User can change PIR sensor or put sensor away of the LSN50 to avoid this happen.

==== 2.3.3.5 Digital Interrupt ====

604

605

Digital Interrupt refers to pin PB14, and there are different trigger methods. When there is a trigger, the SN50v3 will send a packet to the server.

606

607

**~ Interrupt connection method:**

**Example to use with door sensor :**

612

613

The door sensor is shown at right. It is a two wire magnetic contact switch used for detecting the open/close status of doors or windows.

614

615

[[image:http://wiki.dragino.com/xwiki/bin/download/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/LSN50%20%26%20LSN50-V2%20-%20LoRaWAN%20Sensor%20Node%20User%20Manual/WebHome/1656379210849-860.png?rev=1.1||alt="1656379210849-860.png"]]

616

617

When the two pieces are close to each other, the 2 wire output will be short or open (depending on the type), while if the two pieces are away from each other, the 2 wire output will be the opposite status. So we can use LSN50 interrupt interface to detect the status for the door or window.

618

619

**~ Below is the installation example:**

620

621

Fix one piece of the magnetic sensor to the door and connect the two pins to LSN50 as follows:

622

623

* (((

624

One pin to LSN50's PB14 pin

625

)))

626

* (((

627

The other pin to LSN50's VCC pin

628

)))

629

630

Install the other piece to the door. Find a place where the two pieces will be close to each other when the door is closed. For this particular magnetic sensor, when the door is closed, the output will be short, and PB14 will be at the VCC voltage.

631

632

Door sensors have two types: ** NC (Normal close)** and **NO (normal open)**. The connection for both type sensors are the same. But the decoding for payload are reverse, user need to modify this in the IoT Server decoder.

633

634

When door sensor is shorted, there will extra power consumption in the circuit, the extra current is 3v3/R14 = 3v2/1Mohm = 0.3uA which can be ignored.

635

636

[[image:http://wiki.dragino.com/xwiki/bin/download/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/LSN50%20%26%20LSN50-V2%20-%20LoRaWAN%20Sensor%20Node%20User%20Manual/WebHome/1656379283019-229.png?rev=1.1||alt="1656379283019-229.png"]]

637

638

The above photos shows the two parts of the magnetic switch fitted to a door.

639

640

The software by default uses the falling edge on the signal line as an interrupt. We need to modify it to accept both the rising edge (0v ~-~-> VCC , door close) and the falling edge (VCC ~-~-> 0v , door open) as the interrupt.

The command is:

**AT+INTMOD=1 **~/~/(more info about INMOD please refer** **[[**AT Command Manual**>>url:http://www.dragino.com/downloads/index.php?dir=LSN50-LoRaST/&file=DRAGINO_LSN50_AT_Commands_v1.5.1.pdf]]**. **)

649

650

In MOD=1, user can use byte 6 to see the status for door open or close. TTN V3 decoder is as below:

651

652

door= (bytes[6] & 0x80)? "CLOSE":"OPEN";

653

654

655

==== 2.3.3.6 I2C Interface (SHT20 & SHT31) ====

656

657

The SDA and SCK are I2C interface lines. You can use these to connect to an I2C device and get the sensor data.

658

659

We have made an example to show how to use the I2C interface to connect to the SHT20 Temperature and Humidity Sensor.

660

661

Notice: Different I2C sensors have different I2C commands set and initiate process, if user want to use other I2C sensors, User need to re-write the source code to support those sensors. SHT20 code in SN50_v3 will be a good reference.

662

663

Below is the connection to SHT20/ SHT31. The connection is as below:

670

671

Convert the read byte to decimal and divide it by ten.

**Example:**

Temperature: Read:0116(H) = 278(D) Value: 278 /10=27.8℃;

676

677

Humidity: Read:0248(H)=584(D) Value: 584 / 10=58.4, So 58.4%

690

691

The LSN50 detects the pulse width of the sensor and converts it to mm output. The accuracy will be within 1 centimeter. The usable range (the distance between the ultrasonic probe and the measured object) is between 24cm and 600cm.

692

693

The picture below shows the connection:

694

695

696

Connect to the LSN50 and run **AT+MOD=2** to switch to ultrasonic mode (ULT).

697

698

The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.

**Example:**

Distance: Read: 0C2D(Hex) = 3117(D) Value: 3117 mm=311.7 cm

==== 2.3.3.9 Battery Output - BAT pin ====

719

720

The BAT pin of SN50v3 is connected to the Battery directly. If users want to use BAT pin to power an external sensor. User need to make sure the external sensor is of low power consumption. Because the BAT pin is always open. If the external sensor is of high power consumption. the battery of SN50v3-LB will run out very soon.

721

722

723

==== 2.3.3.10 +5V Output ====

724

725

SN50v3 will enable +5V output before all sampling and disable the +5v after all sampling.

726

727

The 5V output time can be controlled by AT Command.

**AT+5VT=1000**

Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.

732

733

By default the AT+5VT=500. If the external sensor which require 5v and require more time to get stable state, user can use this command to increase the power ON duration for this sensor.

==== 2.3.3.11 BH1750 Illumination Sensor ====

738

739

MOD=1 support this sensor. The sensor value is in the 8^^th^^ and 9^^th^^ bytes.

750

User can use the 3^^rd^^ ~~ 7^^th^^ bit of this byte to see the working mod:

751

752
