Edwin Chen 11.2 153 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.

159 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
161 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.

Edwin Chen 14.1 656
657 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.
658
659 [[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"]]
660
Saxer Lin 36.1 661 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.
Edwin Chen 14.1 662
Xiaoling 43.8 663 (% style="color:blue" %)**~ Below is the installation example:**
Edwin Chen 14.1 664
Saxer Lin 36.1 665 Fix one piece of the magnetic sensor to the door and connect the two pins to SN50_v3 as follows:
Edwin Chen 14.1 666
667 * (((
Saxer Lin 36.1 668 One pin to SN50_v3's PA8 pin
Edwin Chen 14.1 669 )))
670 * (((
Saxer Lin 36.1 671 The other pin to SN50_v3's VDD pin
Edwin Chen 14.1 672 )))
673
Saxer Lin 36.1 674 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.
Edwin Chen 14.1 675
676 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.
677
Saxer Lin 36.1 678 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.

681
682 The above photos shows the two parts of the magnetic switch fitted to a door.
683
684 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.
685
686 The command is:

Edwin Chen 14.1 700
Saxer Lin 26.2 701 The SDA and SCK are I2C interface lines. You can use these to connect to an I2C device and get the sensor data.
Edwin Chen 14.1 702
Saxer Lin 40.1 703 We have made an example to show how to use the I2C interface to connect to the SHT20/ SHT31 Temperature and Humidity Sensor.
Edwin Chen 14.1 704
Saxer Lin 40.1 705 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.
Edwin Chen 14.1 706
707 Below is the connection to SHT20/ SHT31. The connection is as below:

Edwin Chen 14.1 735
Saxer Lin 36.1 736 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.
Edwin Chen 14.1 737
Saxer Lin 36.1 738 The working principle of this sensor is similar to the **HC-SR04** ultrasonic sensor.
739
Edwin Chen 14.1 740 The picture below shows the connection:

Edwin Chen 14.1 743
Saxer Lin 36.1 744 Connect to the SN50_v3 and run **AT+MOD=2** to switch to ultrasonic mode (ULT).
Edwin Chen 14.1 745
746 The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.
747
748 **Example:**
749
750 Distance:  Read: 0C2D(Hex) = 3117(D)  Value:  3117 mm=311.7 cm
751
752
753
754 ==== 2.3.3.9  Battery Output - BAT pin ====
755
756 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.
757
758
759 ==== 2.3.3.10  +5V Output ====
760
761 SN50v3 will enable +5V output before all sampling and disable the +5v after all sampling. 
762
763 The 5V output time can be controlled by AT Command.
764
Xiaoling 43.9 765 (% style="color:blue" %)**AT+5VT=1000**
Edwin Chen 14.1 766
767 Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
768
769 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.
