97 -
98 -
99 -The Dragino (% style="color:blue" %)**SDI-12-LB**(%%) is a (% style="color:blue" %)**SDI-12 to LoRaWAN Converter **(%%)designed for Smart Agriculture solution.
100 -
101 -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.
102 -
103 -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.
104 -
105 -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.
106 -
107 -SDI-12-LB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), it is designed for long term use up to 5 years.
108 -
109 -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.

To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and activate the SDI-12-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

852 -Use can configure SDI-12-LB via AT Command or LoRaWAN Downlink.
853 -
854 -* AT Command Connection: See [[FAQ>>path:#AT_COMMAND]].
855 -* LoRaWAN Downlink instruction for different platforms: See [[IoT LoRaWAN Server>>http://wiki.dragino.com/xwiki/bin/view/Main/]] section.
856 -
857 -There are two kinds of commands to configure SDI-12-LB, they are:
858 -
859 -* **General Commands**.
860 -
861 -These commands are to configure:
862 -
863 -* General system settings like: uplink interval.
864 -* LoRaWAN protocol & radio related command.
865 -
866 -They are same for all Dragino Device which support DLWS-005 LoRaWAN Stack. These commands can be found on the wiki:

1139 -=== 4.3.1 ​Battery Note ===
1140 -
1141 -
1142 -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.
1143 -
1144 -
1145 -=== 4.3.2 Replace the battery ===
1146 -
1147 -
1148 -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.
1149 -
1150 -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)
