151

152

153

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.

160

277

278

279

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.

284

286

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

287

288

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.

447

448

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

449

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

482

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.

483

484

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 SN50_v3 to avoid this happen.

==== 2.3.3.5 Digital Interrupt ====

662

663

Digital Interrupt refers to pin PA8, and there are different trigger methods. When there is a trigger, the SN50v3 will send a packet to the server.

666

667

[[image:image-20230513105351-5.png||height="147" width="485"]]

668

669

(% style="color:blue" %)**Example to use with door sensor :**

670

671

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.

672

673

[[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"]]

674

675

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 SN50_v3 interrupt interface to detect the status for the door or window.

676

677

(% style="color:blue" %)**~ Below is the installation example:**

678

679

Fix one piece of the magnetic sensor to the door and connect the two pins to SN50_v3 as follows:

680

681

* (((

682

One pin to SN50_v3's PA8 pin

683

)))

684

* (((

685

The other pin to SN50_v3's VDD pin

686

)))

687

688

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 PA8 will be at the VCC voltage.

689

690

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.

691

692

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

693

694

695

696

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

697

698

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:

707

708

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

709

710

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

711

712

713

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

714

715

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

716

717

We have made an example to show how to use the I2C interface to connect to the SHT20/ SHT31 Temperature and Humidity Sensor.

718

719

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/ SHT31 code in SN50_v3 will be a good reference.

720

721

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

722

723

724

[[image:image-20230513103633-3.png||height="448" width="716"]]

725

726

The device will be able to get the I2C sensor data now and upload to IoT Server.

727

728

[[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/1656379664142-345.png?rev=1.1||alt="1656379664142-345.png"]]

729

730

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

**Example:**

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

735

736

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

737

738

If you want to use other I2C device, please refer the SHT20 part source code as reference.

747

748

This Fundamental Principles of this sensor can be found at this link: [[https:~~/~~/wiki.dfrobot.com/Weather_-_proof_Ultrasonic_Sensor_with_Separate_Probe_SKU~~_~~__SEN0208>>url:https://wiki.dfrobot.com/Weather_-_proof_Ultrasonic_Sensor_with_Separate_Probe_SKU___SEN0208]]

749

750

The SN50_v3 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.

751

752

The working principle of this sensor is similar to the **HC-SR04** ultrasonic sensor.

753

754

The picture below shows the connection:

755

756

[[image:image-20230512173903-6.png||height="596" width="715"]]

757

758

Connect to the SN50_v3 and run **AT+MOD=2** to switch to ultrasonic mode (ULT).

759

760

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 ====

769

770

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.

771

772

773

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

774

775

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

776

777

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

778

779

(% style="color:blue" %)**AT+5VT=1000**

780

781

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

782

783

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 ====
