605 ==== 2.3.3.5 Digital Interrupt ====
606
607 Digital Interrupt refers to pin PB14, and there are different trigger methods. When there is a trigger, the SN50v3 will send a packet to the server.
608
609 **~ Interrupt connection method:**
610
611 [[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/1656379178634-321.png?rev=1.1||alt="1656379178634-321.png"]]
612
613 **Example to use with door sensor :**
614
615 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.
616
617 [[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"]]
618
619 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 LSN50 interrupt interface to detect the status for the door or window.
620
621 **~ Below is the installation example:**
622
623 Fix one piece of the magnetic sensor to the door and connect the two pins to LSN50 as follows:
624
625 * (((
626 One pin to LSN50's PB14 pin
627 )))
628 * (((
629 The other pin to LSN50's VCC pin
630 )))
631
632 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 PB14 will be at the VCC voltage.
633
634 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.
635
636 When door sensor is shorted, there will extra power consumption in the circuit, the extra current is 3v3/R14 = 3v2/1Mohm = 0.3uA which can be ignored.

640 The above photos shows the two parts of the magnetic switch fitted to a door.
641
642 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.
643
644 The command is:
645
646 **AT+INTMOD=1       **~/~/(more info about INMOD please refer** **[[**AT Command Manual**>>url:http://www.dragino.com/downloads/index.php?dir=LSN50-LoRaST/&file=DRAGINO_LSN50_AT_Commands_v1.5.1.pdf]]**. **)

651
652 In MOD=1, user can use byte 6 to see the status for door open or close. TTN V3 decoder is as below:
653
654 door= (bytes[6] & 0x80)? "CLOSE":"OPEN";
655
656 **Notice for hardware version LSN50 v1 < v1.3** (produced before 2018-Nov).
657
658 In this hardware version, there is no R14 resistance solder. When use the latest firmware, it should set AT+INTMOD=0 to close the interrupt. If user need to use Interrupt in this hardware version, user need to solder R14 with 10M resistor and C1 (0.1uF) on board.

663 ==== 2.3.3.6 I2C Interface (SHT20) ====
664
665 The PB6(SDA) and PB7(SCK) are I2C interface lines. You can use these to connect to an I2C device and get the sensor data.
666
667 We have made an example to show how to use the I2C interface to connect to the SHT20 Temperature and Humidity Sensor. This is supported in the stock firmware since v1.5 with **AT+MOD=1 (default value).**
668
669 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 code in LSN50 will be a good reference.
670
671 Below is the connection to SHT20/ SHT31. The connection is as below:

679 Convert the read byte to decimal and divide it by ten.
680
681 **Example:**
682
683 Temperature:  Read:0116(H) = 278(D)  Value:  278 /10=27.8℃;
684
685 Humidity:    Read:0248(H)=584(D)  Value:  584 / 10=58.4, So 58.4%

695 ==== 2.3.3.8 Ultrasonic Sensor ====
696
697 The LSN50 v1.5 firmware supports ultrasonic sensor (with AT+MOD=2) such as SEN0208 from DF-Robot. 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]]
698
699 The LSN50 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.
700
701 The picture below shows the connection:
702
703 [[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/1656380061365-178.png?rev=1.1||alt="1656380061365-178.png"]]
704
705 Connect to the LSN50 and run **AT+MOD=2** to switch to ultrasonic mode (ULT).
706
707 The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.
708

727 ==== 2.3.3.9  Battery Output - BAT pin ====
728
729 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.
730
731
732 ==== 2.3.3.10  +5V Output ====
733
734 SN50v3 will enable +5V output before all sampling and disable the +5v after all sampling. 
735
736 The 5V output time can be controlled by AT Command.
737
738 **AT+5VT=1000**
739
740 Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
741
742 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.
