70 The Dragino LDDS75 is a (% style="color:#4472c4" %)** 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:#4472c4" %)** ultrasonic sensing** (%%)technology for distance measurement, and (% style="color:#4472c4" %)** temperature compensation**(%%) is performed internally to improve the reliability of data. The LDDS75 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.
71
72
73 It detects the distance** (% style="color:#4472c4" %) between the measured object and the sensor(%%)**, and uploads the value via wireless to LoRaWAN IoT Server.
74
75
76 The LoRa wireless technology used in LDDS75 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.
77
78
79 LDDS75 is powered by (% style="color:#4472c4" %)** 4000mA or 8500mAh Li-SOCI2 battery**(%%); It is designed for long term use up to 10 years*.
80
81
82 Each LDDS75 pre-loads with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect if there is network coverage, after power on.

163 The LDDS75 is configured as LoRaWAN OTAA Class A mode by default. It has OTAA keys to join LoRaWAN network. To connect a LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and power on the LDDS75. If there is coverage of the LoRaWAN network, it will automatically join the network via OTAA and start to send the sensor value

280
281 === 2.3.2  Distance ===
282
283 Get the distance. Flat object range 280mm - 7500mm.
284
285 For example, if the data you get from the register is 0x0B 0x05, the distance between the sensor and the measured object is(% style="color:#4472c4" %)** 0B05(H) = 2821 (D) = 2821 mm.**
286
287
288 * If the sensor value is 0x0000, it means system doesn’t detect ultrasonic sensor.
289 * If the sensor value lower than 0x0118 (280mm), the sensor value will be invalid. Since v1.1.4, all value lower than 280mm will be set to 0x0014(20mm) which means the value is invalid.

304
305 This is optional, user can connect external DS18B20 sensor to the +3.3v, 1-wire and GND pin . and this field will report temperature.
306
307 **Example**:
308
309 If payload is: 0105H:  (0105 & FC00 == 0), temp = 0105H /10 = 26.1 degree
310
311 If payload is: FF3FH :  (FF3F & FC00 == 1) , temp = (FF3FH - 65536)/10 = -19.3 degrees.

On the main board, there is a diode (D1) between the battery and the main circuit. If you need to use a battery with less than 3.3v, please remove the D1 and shortcut the two pads of it so there won’t be voltage drop between battery and main board.

1061
1062 == 4.1  What is the frequency plan for LDDS75? ==
1063
1064 LDDS75 use the same frequency as other Dragino products. User can see the detail from this link:  [[Introduction>>path:/xwiki/bin/view/Main/End%20Device%20Frequency%20Band/#H1.Introduction]]

1074
1075 == 4.3  Can I use LDDS75 in condensation environment? ==
1076
1077 LDDS75 is not suitable to be used in condensation environment. Condensation on the LDDS75 probe will affect the reading and always got 0.

1083 == 5.1  Why I can’t join TTN V3 in US915 / AU915 bands? ==
1084
1085 It is due to channel mapping. Please see below link:  [[Frequency band>>path:/xwiki/bin/view/Main/LoRaWAN%20Communication%20Debug/#H2.NoticeofUS9152FCN4702FAU915Frequencyband]]

1088 == 5.2  AT Command input doesn't work ==
1089
1090 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:green" %)**ENTER**(%%) while sending out the command. Some serial tool doesn’t send (% style="color:green" %)**ENTER**(%%) while press the send key, user need to add ENTER in their string.
