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 14.1 638
639 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.
640
641 [[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"]]
642
Saxer Lin 36.1 643 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 14.1 644
Xiaoling 43.8 645 (% style="color:blue" %)**~ Below is the installation example:**
Edwin Chen 14.1 646
Saxer Lin 36.1 647 Fix one piece of the magnetic sensor to the door and connect the two pins to SN50_v3 as follows:

Edwin Chen 14.1 651 )))
652 * (((
Saxer Lin 36.1 653 The other pin to SN50_v3's VDD pin
Edwin Chen 14.1 654 )))
655
Saxer Lin 36.1 656 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 14.1 657
658 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.
659
Saxer Lin 36.1 660 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.

Edwin Chen 14.1 717
Saxer Lin 36.1 718 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 14.1 719
Saxer Lin 36.1 720 The working principle of this sensor is similar to the **HC-SR04** ultrasonic sensor.

Saxer Lin 36.1 726 Connect to the SN50_v3 and run **AT+MOD=2** to switch to ultrasonic mode (ULT).
Edwin Chen 14.1 727
728 The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.
729
730 **Example:**

736 ==== 2.3.3.9  Battery Output - BAT pin ====
737
738 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.
739
740
741 ==== 2.3.3.10  +5V Output ====
742
743 SN50v3 will enable +5V output before all sampling and disable the +5v after all sampling. 
744
745 The 5V output time can be controlled by AT Command.
746
Xiaoling 43.9 747 (% style="color:blue" %)**AT+5VT=1000**
Edwin Chen 14.1 748
749 Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
750
751 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.
