149
Edwin Chen 11.2 150 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.

154
155
156 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.
157
158 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.

712
Saxer Lin 36.1 713 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 14.1 714
715 **~ Below is the installation example:**
716
Saxer Lin 36.1 717 Fix one piece of the magnetic sensor to the door and connect the two pins to SN50_v3 as follows:
Edwin Chen 14.1 718
719 * (((
Saxer Lin 36.1 720 One pin to SN50_v3's PA8 pin
Edwin Chen 14.1 721 )))
722 * (((
Saxer Lin 36.1 723 The other pin to SN50_v3's VDD pin
Edwin Chen 14.1 724 )))
725
Saxer Lin 36.1 726 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 14.1 727
728 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.
729
Saxer Lin 36.1 730 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.

733
734 The above photos shows the two parts of the magnetic switch fitted to a door.
735
736 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.
737
738 The command is:

Edwin Chen 14.1 752
Saxer Lin 26.2 753 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 14.1 754
Saxer Lin 40.1 755 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 14.1 756
Saxer Lin 40.1 757 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 14.1 758
759 Below is the connection to SHT20/ SHT31. The connection is as below:

785
Saxer Lin 26.2 786 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]]
Edwin Chen 14.1 787
Saxer Lin 36.1 788 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 14.1 789
Saxer Lin 36.1 790 The working principle of this sensor is similar to the **HC-SR04** ultrasonic sensor.
791
Edwin Chen 14.1 792 The picture below shows the connection:
793
Saxer Lin 36.1 794 [[image:image-20230512173903-6.png||height="596" width="715"]]
Edwin Chen 14.1 795
Saxer Lin 36.1 796 Connect to the SN50_v3 and run **AT+MOD=2** to switch to ultrasonic mode (ULT).
Edwin Chen 14.1 797
798 The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.
799
800 **Example:**
801
802 Distance:  Read: 0C2D(Hex) = 3117(D)  Value:  3117 mm=311.7 cm
803
804
805
806 ==== 2.3.3.9  Battery Output - BAT pin ====
807
808 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.
809
810
811 ==== 2.3.3.10  +5V Output ====
812
813 SN50v3 will enable +5V output before all sampling and disable the +5v after all sampling. 
814
815 The 5V output time can be controlled by AT Command.
816
817 **AT+5VT=1000**
818
819 Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
820
821 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.
822
823
