43 SN50v3-LB/LS has different working mode for the connections of different type of sensors. This section describes these modes. Use can use the AT Command (% style="color:blue" %)**AT+MOD**(%%) to set SN50v3-LB/LS to different working modes.
44
45 For example:

577
578 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.

581 (% style="color:blue" %)**Below is the installation example:**
582
583 Fix one piece of the magnetic sensor to the door and connect the two pins to SN50v3-LB/LS as follows:
584
585 * (((
586 One pin to SN50v3-LB/LS's PA8 pin
587 )))
588 * (((
589 The other pin to SN50v3-LB/LS's VDD pin
590 )))
591
592 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.
593
594 Door sensors have two types: (% style="color:blue" %)** NC (Normal close)**(%%) and (% style="color:blue" %)**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.
595
596 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.

600 The above photos shows the two parts of the magnetic switch fitted to a door.
601
602 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.

617 === 2.2.6 I2C Interface (SHT20 & SHT31) ===
618
619
620 The SDA and SCK are I2C interface lines. You can use these to connect to an I2C device and get the sensor data.
621
622 We have made an example to show how to use the I2C interface to connect to the SHT20/ SHT31 Temperature and Humidity Sensor.
623
624 (% style="color:red" %)**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 SN50v3-LB/LS will be a good reference.**
625
626
627 Below is the connection to SHT20/ SHT31. The connection is as below:

631 The device will be able to get the I2C sensor data now and upload to IoT Server.

634
635 Convert the read byte to decimal and divide it by ten.
636
637 **Example:**
638
639 Temperature:  Read:0116(H) = 278(D)  Value:  278 /10=27.8℃;
640
641 Humidity:    Read:0248(H)=584(D)  Value:  584 / 10=58.4, So 58.4%

655 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]]
656
657 The SN50v3-LB/LS 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.
658
659 The working principle of this sensor is similar to the (% style="color:blue" %)**HC-SR04**(%%) ultrasonic sensor.
660
661 The picture below shows the connection:
662

664
665 Connect to the SN50v3-LB/LS and run (% style="color:blue" %)**AT+MOD=2**(%%) to switch to ultrasonic mode (ULT).
666
667 The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.
668
669 **Example:**
670
671 Distance:  Read: 0C2D(Hex) = 3117(D)  Value:  3117 mm=311.7 cm
672
673
674 === 2.2.9 Battery Output - BAT pin ===
675
676
677 The BAT pin of SN50v3-LB/LS 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/LS will run out very soon.
678
679
680 === 2.2.10 +5V Output ===
681
682
683 SN50v3-LB/LS will enable +5V output before all sampling and disable the +5v after all sampling. 
684
685 The 5V output time can be controlled by AT Command.
686
687 (% style="color:blue" %)**AT+5VT=1000**
688
689 Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
690
691 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.
692
693
694 === 2.2.11 BH1750 Illumination Sensor ===

711 If the PWM pin connected to the SDA pin cannot maintain a high level when it is not working, you need to remove the resistor R2 or replace it with a resistor with a larger resistance, otherwise a sleep current of about 360uA will be generated.

720 Since the device can only detect a pulse period of 50ms when [[AT+PWMSET=0>>||anchor="H3.3.8PWMsetting"]] (counting in microseconds), it is necessary to change the value of PWMSET according to the frequency of input capture.

725 For PWM Output Feature, there are two consideration to see if the device can be powered by battery or have to be powered by external DC.
726
727 a) If real-time control output is required, the SN50v3-LB/LS is already operating in class C and an external power supply must be used.

759 PS-LB-NA might connect to different kind of probes, 4~~20mA represent the full scale of the measuring range. So a 12mA output means different meaning for different probe.
