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.

)))

(((

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.

)))

(((

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.

)))

(((

SDI-12-LB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), it is designed for long term use up to 5 years.

)))

(((

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.

187

188

189

The SDI-12-LB is configured as (% style="color:#037691" %)**LoRaWAN OTAA Class A**(%%) mode by default. It has OTAA keys to join LoRaWAN network. 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.

253

254

=== 2.3.1 Basic SDI-12 debug command ===

255

256

257

User can run some basic SDI-12 command to debug the connection to the SDI-12 sensor. These commands can be sent via AT Command or LoRaWAN downlink command.

258

259

If SDI-12 sensor return value after get these commands, //SDI-12-LB// will uplink the return on FPORT=100, otherwise, if there is no response from SDI-12 sensor. //SDI-12-LB// will uplink NULL (0x 4E 55 4C 4C) to server.

SDI-12-LB is equipped with a [[8500mAH ER26500 Li-SOCI2 battery>>https://www.dropbox.com/sh/w9l2oa3ytpculph/AAAPtt-apH4lYfCj-2Y6lHvQa?dl=0]]. 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.

1091

1092

1093

The discharge curve is not linear so can’t simply use percentage to show the battery level. Below is the battery performance.

1103

== 4.2 Replace Battery ==

1104

1105

1106

Any battery with range 2.45 ~~ 3.6v can be a replacement. We recommend to use Li-SOCl2 Battery.

1108

And make sure the positive and negative pins match.

=== 4.3.1 Battery Note ===

1142

1143

1144

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.

1145

1146

1147

=== 4.3.2 Replace the battery ===

1148

1149

1150

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.

1151

1152

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)
