Introduction = 20 + 21 +== 1.1 What is SDI-12 to LoRaWAN Converter == 22 + 23 + 24 +The Dragino **SDI-12-LB** is a **SDI-12 to LoRaWAN Converter **designed for Smart Agriculture solution. 25 + 26 +SDI-12 (Serial Digital Interface at 1200 baud) is an asynchronous [[serial communications>>url:https://en.wikipedia.org/wiki/Serial_communication]] protocol for intelligent sensors that monitor environment data. SDI-12 protocol is widely used in Agriculture sensor and Weather Station sensors. 27 + 28 +**SDI-12-LB** has SDI-12 interface and support 12v output to power external SDI-12 sensor. It can get the environment data from SDI-12 sensor and sends out the data via LoRaWAN wireless protocol. 29 + 30 +The LoRa wireless technology used in **SDI-12-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. 31 + 32 +**SDI-12-LB** is powered by **8500mAh Li-SOCI2 battery**, it is designed for long term use up to 5 years. 33 + 34 +Each **SDI-12-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. 35 + 36 + 37 +[[image:image-20230201084414-1.png||height="464" width="1108"]] 38 + 39 + 40 + 41 + 42 + 43 + 44 +== 1.2 Features == 45 + 46 + 47 +* LoRaWAN 1.0.3 Class A 48 +* Ultra-low power consumption 49 +* Controllable 5v and 12v output to power external sensor 50 +* SDI-12 Protocol to connect to SDI-12 Sensor 51 +* Monitor Battery Level 52 +* Bands: CN470/EU433/KR920/US915/EU868/AS923/AU915/IN865 53 +* Support Bluetooth v5.1 and LoRaWAN remote configure. 54 +* Support wireless OTA update firmware 55 +* Uplink on periodically 56 +* Downlink to change configure 57 +* 8500mAh Battery for long term use 58 + 59 +== 1.3 Specification == 60 + 61 + 62 +**Micro Controller:** 63 + 64 +* MCU: 48Mhz ARM 65 +* Flash: 256KB 66 +* RAM: 64KB 67 + 68 +**Common DC Characteristics:** 69 + 70 +* Supply Voltage: 2.5v ~~ 3.6v 71 +* Operating Temperature: -40 ~~ 85°C 72 + 73 +**LoRa Spec:** 74 + 75 +* Frequency Range, Band 1 (HF): 862 ~~ 1020 Mhz 76 +* Max +22 dBm constant RF output vs. 77 +* RX sensitivity: down to -139 dBm. 78 +* Excellent blocking immunity 79 + 80 +**Current Input Measuring :** 81 + 82 +* Range: 0 ~~ 20mA 83 +* Accuracy: 0.02mA 84 +* Resolution: 0.001mA 85 + 86 +**Voltage Input Measuring:** 87 + 88 +* Range: 0 ~~ 30v 89 +* Accuracy: 0.02v 90 +* Resolution: 0.001v 91 + 92 +**Battery:** 93 + 94 +* Li/SOCI2 un-chargeable battery 95 +* Capacity: 8500mAh 96 +* Self-Discharge: <1% / Year @ 25°C 97 +* Max continuously current: 130mA 98 +* Max boost current: 2A, 1 second 99 + 100 +**Power Consumption** 101 + 102 +* Sleep Mode: 5uA @ 3.3v 103 +* LoRa Transmit Mode: 125mA @ 20dBm, 82mA @ 14dBm 104 + 105 +== 1.4 Connect to SDI-12 Sensor == 106 + 107 + 108 + 109 +[[image:1675212538524-889.png]] 110 + 111 + 112 +== 1.5 Sleep mode and working mode == 113 + 114 + 115 +**Deep Sleep Mode: **Sensor doesn't have any LoRaWAN activate.

Battery & how to replace 1225 +11. Battery Type 1226 + 1227 +SDI-12-LB is equipped with a [[8500mAH ER26500 Li-SOCI2 battery>>url:https://www.dragino.com/downloads/index.php?dir=datasheet/Battery/ER26500/]]. The battery is un-rechargeable battery with low discharge rate targeting for 8~~10 years use. This type of battery is commonly used in IoT target for long-term running, such as water meter. 1228 + 1229 + 1230 +The discharge curve is not linear so can’t simply use percentage to show the battery level. Below is the battery performance. 1231 + 1232 +[[image:file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image036.png]] 1233 + 1234 + 1235 +Minimum Working Voltage for the SDI-12-LB: 1236 + 1237 +SDI-12-LB: 2.45v ~~ 3.6v 1238 + 1239 + 1240 +1. 1241 +11. Replace Battery 1242 + 1243 +Any battery with range 2.45 ~~ 3.6v can be a replacement. We recommend to use Li-SOCl2 Battery. 1244 + 1245 +And make sure the positive and negative pins match. 1246 + 1247 + 1248 + 1249 +1. 1250 +11. Power Consumption Analyze 1251 + 1252 +Dragino Battery powered product are all runs in Low Power mode. We have an update battery calculator which base on the measurement of the real device. User can use this calculator to check the battery life and calculate the battery life if want to use different transmit interval. 1253 + 1254 + 1255 +Instruction to use as below: 1256 + 1257 + 1258 +Step 1: Downlink the up-to-date DRAGINO_Battery_Life_Prediction_Table.xlsx from: 1259 + 1260 +[[https:~~/~~/www.dragino.com/downloads/index.php?dir=LoRa_End_Node/Battery_Analyze/>>url:https://www.dragino.com/downloads/index.php?dir=LoRa_End_Node/Battery_Analyze/]] 1261 + 1262 + 1263 +Step 2: Open it and choose 1264 + 1265 +* Product Model 1266 +* Uplink Interval 1267 +* Working Mode 1268 + 1269 +And the Life expectation in difference case will be shown on the right. 1270 + 1271 +[[image:file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image037.png]] 1272 + 1273 + 1274 +The battery related documents as below: 1275 + 1276 +* [[Battery Dimension>>url:http://www.dragino.com/downloads/index.php?dir=datasheet/Battery/&file=LSN50-Battery-Dimension.pdf]], 1277 +* [[Lithium-Thionyl Chloride Battery>>url:http://www.dragino.com/downloads/downloads/datasheet/Battery/ER18505_datasheet-EN.pdf]] datasheet, [[Tech Spec>>url:http://www.dragino.com/downloads/downloads/datasheet/Battery/ER18505_datasheet_PM-ER18505-S-02-LF_EN.pdf]] 1278 +* [[Lithium-ion Battery-Capacitor datasheet>>url:http://www.dragino.com/downloads/downloads/datasheet/Battery/SPC_1520_datasheet.jpg]], [[Tech Spec>>url:http://www.dragino.com/downloads/downloads/datasheet/Battery/SPC1520%20Technical%20Specification20171123.pdf]] 1279 + 1280 +|((( 1281 +JST-XH-2P connector 1282 +))) 1283 + 1284 +[[image:file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image038.png]] 1285 + 1286 + 1287 + 1288 +1. 1289 +11. 1290 +111. Battery Note 1291 + 1292 +The Li-SICO battery is designed for small current / long period application. It is not good to use a high current, short period transmit method. The recommended minimum period for use of this battery is 5 minutes. If you use a shorter period time to transmit LoRa, then the battery life may be decreased. 1293 + 1294 + 1295 +1. 1296 +11. 1297 +111. Replace the battery 1298 + 1299 +You can change the battery in the SDI-12-LB.The type of battery is not limited as long as the output is between 3v to 3.6v. 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. 1300 + 1301 + 1302 +The default battery pack of SDI-12-LB includes a ER26500 plus super capacitor. If user can’t find this pack locally, they can find ER26500 or equivalence, which will also work in most case. The SPC can enlarge the battery life for high frequency use (update period below 5 minutes) 1303 + 1304 + 1305 + 1306 + 1307 + 1308 + 1309 +1. Remote Configure device 1310 +11.
