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.

Saxer Lin 36.1 670 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 14.1 671
Xiaoling 43.8 672 (% style="color:blue" %)**~ Below is the installation example:**
Edwin Chen 14.1 673
Saxer Lin 36.1 674 Fix one piece of the magnetic sensor to the door and connect the two pins to SN50_v3 as follows:
Edwin Chen 14.1 675
676 * (((
Saxer Lin 36.1 677 One pin to SN50_v3's PA8 pin
Edwin Chen 14.1 678 )))
679 * (((
Saxer Lin 36.1 680 The other pin to SN50_v3's VDD pin
Edwin Chen 14.1 681 )))
682
Saxer Lin 36.1 683 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 14.1 684
685 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.
686
Saxer Lin 36.1 687 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.

691 The above photos shows the two parts of the magnetic switch fitted to a door.
692
693 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.
694
695 The command is:

Saxer Lin 26.2 708 ==== 2.3.3.6 I2C Interface (SHT20 & SHT31) ====
Edwin Chen 14.1 709
Saxer Lin 26.2 710 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 14.1 711
Saxer Lin 40.1 712 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 14.1 713
Saxer Lin 40.1 714 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 14.1 715
716 Below is the connection to SHT20/ SHT31. The connection is as below:

725 Convert the read byte to decimal and divide it by ten.
726
Edwin Chen 2.1 727 **Example:**
728
Edwin Chen 14.1 729 Temperature:  Read:0116(H) = 278(D)  Value:  278 /10=27.8℃;
Edwin Chen 2.1 730

742
Saxer Lin 26.2 743 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 14.1 744
Saxer Lin 36.1 745 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 14.1 746
Saxer Lin 36.1 747 The working principle of this sensor is similar to the **HC-SR04** ultrasonic sensor.
748
Edwin Chen 14.1 749 The picture below shows the connection:
750
Saxer Lin 36.1 751 [[image:image-20230512173903-6.png||height="596" width="715"]]
Edwin Chen 14.1 752
Saxer Lin 36.1 753 Connect to the SN50_v3 and run **AT+MOD=2** to switch to ultrasonic mode (ULT).
Edwin Chen 14.1 754
755 The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.
756
757 **Example:**
758
759 Distance:  Read: 0C2D(Hex) = 3117(D)  Value:  3117 mm=311.7 cm
760
761
762
763 ==== 2.3.3.9  Battery Output - BAT pin ====
764
765 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.
766
767
768 ==== 2.3.3.10  +5V Output ====
769
770 SN50v3 will enable +5V output before all sampling and disable the +5v after all sampling. 
771
772 The 5V output time can be controlled by AT Command.
773
Xiaoling 43.9 774 (% style="color:blue" %)**AT+5VT=1000**
Edwin Chen 14.1 775
776 Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
777
778 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.
779
