619 -
620 -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.
621 -
622 -**~ Below is the installation example:**
623 -
624 -Fix one piece of the magnetic sensor to the door and connect the two pins to LSN50 as follows:
625 -
626 -* (((
627 -One pin to LSN50's PB14 pin
628 -)))
629 -* (((
630 -The other pin to LSN50's VCC pin
631 -)))
632 -
633 -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.
634 -
635 -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.
636 -
637 -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.

702 -The picture below shows the connection:

706 -Connect to the LSN50 and run **AT+MOD=2** to switch to ultrasonic mode (ULT).
707 -
708 -The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.

728 -==== 2.3.3.9  Battery Output - BAT pin ====
729 -
730 -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.
731 -
732 -
733 -==== 2.3.3.10  +5V Output ====
734 -
735 -SN50v3 will enable +5V output before all sampling and disable the +5v after all sampling. 
736 -
737 -The 5V output time can be controlled by AT Command.
738 -
739 -**AT+5VT=1000**
740 -
741 -Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
742 -
743 -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.

747 -==== 2.3.3.11  BH1750 Illumination Sensor ====
748 -
749 -MOD=1 support this sensor. The sensor value is in the 8^^th^^ and 9^^th^^ bytes.
