1.1	19
39.6	20
70.4	21	The Dragino DDS75-LB is a (% style="color:blue" %) LoRaWAN Distance Detection Sensor(%%) for Internet of Things solution. It is used to measure the distance between the sensor and a flat object. The distance detection sensor is a module that uses (% style="color:blue" %) ultrasonic sensing technology(%%) for (% style="color:blue" %)distance measurement(%%), and (% style="color:blue" %) temperature compensation(%%) is performed internally to improve the reliability of data. The DDS75-LB can be applied to scenarios such as horizontal distance measurement, liquid level measurement, parking management system, object proximity and presence detection, intelligent trash can management system, robot obstacle avoidance, automatic control, sewer, bottom water level monitoring, etc.
1.1	22
70.4	23	It detects the distance(% style="color:blue" %) between the measured object and the sensor(%%), and uploads the value via wireless to LoRaWAN IoT Server.
1.1	24
70.14	25	The LoRa wireless technology used in DDS75-LB allows device to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.
1.1	26
70.14	27	DDS75-LB (% style="color:blue" %)supports BLE configure(%%) and (% style="color:blue" %)wireless OTA update(%%) which make user easy to use.
62.4	28
70.14	29	DDS75-LB is powered by (% style="color:blue" %)8500mAh Li-SOCI2 battery(%%), it is designed for long term use up to 5 years.
1.1	30
70.14	31	Each DDS75-LB is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on.

1.1	652
70.14	653	== 6.1 What is the frequency plan for DDS75-LB? ==
1.1	654
62.7	655
70.14	656	DDS75-LB use the same frequency as other Dragino products. User can see the detail from this link: [[Introduction>>doc:Main.End Device Frequency Band.WebHome\|\|anchor="H1.Introduction"]]

1.1	658
70.14	659	== 6.2 Can I use DDS75-LB in condensation environment? ==
1.1	660
	661
70.14	662	DDS75-LB is not suitable to be used in condensation environment. Condensation on the DDS75-LB probe will affect the reading and always got 0.

	666
	667	== 7.1 Why I can't join TTN V3 in US915 / AU915 bands? ==
	668
	669
	670	It is due to channel mapping. Please see below link: [[Frequency band>>doc:Main.LoRaWAN Communication Debug.WebHome\|\|anchor="H2.NoticeofUS9152FCN4702FAU915Frequencyband"]]
	671
	672
	673	== 7.2 AT Command input doesn't work ==
	674
	675
	676	In the case if user can see the console output but can't type input to the device. Please check if you already include the (% style="color:blue" %)ENTER(%%) while sending out the command. Some serial tool doesn't send (% style="color:blue" %)ENTER(%%) while press the send key, user need to add ENTER in their string.
	677
	678
	679	== 7.3 Why does the sensor reading show 0 or "No sensor" ==
	680
	681
	682	~1. The measurement object is very close to the sensor, but in the blind spot of the sensor.
	683
	684	2. Sensor wiring is disconnected
	685
	686	3. Not using the correct decoder
	687
	688
70.17	689	== 7.4 Abnormal readings The gap between multiple readings is too large or the gap between the readings and the actual value is too large ==
70.14	690
	691
	692	1) Please check if there is something on the probe affecting its measurement (condensed water, volatile oil, etc.)
	693
	694	2) Does it change with temperature, temperature will affect its measurement
	695
	696	3) If abnormal data occurs, you can turn on DEBUG mode, Please use downlink or AT COMMAN to enter DEBUG mode.
	697
	698	downlink command: (% style="color:blue" %)F1 01(%%), AT command: (% style="color:blue" %)AT+DDEBUG=1
	699
	700	4) After entering the debug mode, it will send 20 pieces of data at a time, and you can send its uplink to us for analysis
