657 -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.

353 +=== 2.5.1 Ways to get datalog via LoRaWAN ===
671 671  
672 -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.
673 673  
674 -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.

728 -==== 2.3.3.8 Ultrasonic Sensor ====
416 +* Each data entry is 11 bytes, to save airtime and battery, devices will send max bytes according to the current DR and Frequency bands.
729 729  
730 -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]]
418 +For example, in US915 band, the max payload for different DR is:
731 731  
732 -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.
420 +**a) DR0:** max is 11 bytes so one entry of data
733 733  
734 -The working principle of this sensor is similar to the **HC-SR04** ultrasonic sensor.
422 +**b) DR1:** max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
735 735  
736 -The picture below shows the connection:
424 +**c) DR2:** total payload includes 11 entries of data
737 737  
738 -[[image:image-20230512173903-6.png||height="596" width="715"]]
426 +**d) DR3: **total payload includes 22 entries of data.
739 739  
740 -Connect to the SN50_v3 and run **AT+MOD=2** to switch to ultrasonic mode (ULT).
428 +If devise doesn't have any data in the polling time. Device will uplink 11 bytes of 0   
741 741  
742 -The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.
743 743  
744 744  **Example:**
745 745  
746 -Distance:  Read: 0C2D(Hex) = 3117(D)  Value:  3117 mm=311.7 cm

439 +Where : Start time: 60065F97 = time 21/1/19 04:27:03
751 751  
752 -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.
