PS-LB -- LoRaWAN Air Water Pressure Sensor User Manual

The Dragino PS-LB series sensors are **LoRaWAN Pressure Sensor** for Internet of Things solution. PS-LB can measure Air, Water pressure and liquid level and upload the sensor data via wireless to LoRaWAN IoT server.

27

28

The PS-LB series sensors include **Thread Installation Type** and **Immersion Type**, it supports different pressure range which can be used for different measurement requirement.

29

30

The LoRa wireless technology used in PS-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

PS-LB supports BLE configure and wireless OTA update which make user easy to use.

33

34

PS-LB is powered by **8500mAh Li-SOCI2 battery**, it is designed for long term use up to 5 years.

35

36

Each PS-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. Configure PS-LB to connect to LoRaWAN network

254

11. How it works

255

256

The PS-LB is configured as **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 PS-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

1.

11. Quick guide to connect to LoRaWAN server (OTAA)

261

262

Following is an example for how to join the [[TTN v3 LoRaWAN Network>>url:https://console.cloud.thethings.network/]]. Below is the network structure; we use the [[LPS8v2>>url:https://www.dragino.com/products/lora-lorawan-gateway/item/228-lps8v2.html]] as a LoRaWAN gateway in this example.

263

264

265

[[image:file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image003.png]]

266

267

268

The LPS8V2 is already set to connected to [[TTN network >>url:https://console.cloud.thethings.network/]], so what we need to now is configure the TTN server.

269

270

271

**Step 1**: Create a device in TTN with the OTAA keys from PS-LB.

272

273

Each PS-LB is shipped with a sticker with the default device EUI as below:

274

275

276

[[image:file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image015.png]]

You can enter this key in the LoRaWAN Server portal. Below is TTN screen shot:

283

284

285

**Register the device**

**Add APP KEY**

305

306

307

**Step 2**: Activate on PS-LB

308

309

310

Press the button for 5 seconds to activate the PS-LB.

311

312

313

**Green led** will fast blink 5 times, device will enter **OTA mode** for 3 seconds. And then start to JOIN LoRaWAN network. **Green led** will solidly turn on for 5 seconds after joined in network.

314

315

316

After join success, it will start to upload messages to TTN and you can see the messages in the panel.

11. Uplink Payload

Uplink payloads have two types:

328

329

* Distance Value: Use FPORT=2

330

* Other control commands: Use other FPORT fields.

331

332

The application server should parse the correct value based on FPORT settings.

1.

11.

111. Device Status, FPORT=5

339

340

Include device configure status. Once PS-LB Joined the network, it will uplink this message to the server.

341

342

343

Users can also use the downlink command(0x26 01) to ask PS-LB to resend this uplink.

11.

111. Probe Model

PS-LB has different kind of probe, 0~~20mA represent the full scale of the measuring range. So a 15mA output means different meaning for different probe.

For example.

|**Part Number**|**Probe Used**|**0~~20mA scale**|**Example: 10mA meaning**

453

|PS-LB-I3|immersion type with 3 meters cable|0~~3 meters|1.5 meters pure water

454

|PS-LB-I5|immersion type with 5 meters cable|0~~5 meters|2.5 meters pure water

455

456

The probe model field provides the convenient for server to identical how it should parse the 0~~20mA sensor value and get the correct value.

1.

11.

111. 0~~20mA value (IDC_IN)

462

463

The output value from Pressure Probe, use together with Probe Model to get the pressure value or water level.

**Example**:

27AE(H) = 10158 (D)/1000 = 10.158mA.

1.

11.

111. 0~~30V value ( pin VDC_IN)

474

475

Measure the voltage value. The range is 0 to 30V.

**Example**:

138E(H) = 5006(D)/1000= 5.006V

1.

11.

111. IN1&IN2&INT pin

IN1 and IN2 are used as digital input pins.

**Example**:

09 (H) :(0x09&0x08)>>3=1 IN1 pin is high level.

492

493

09 (H) :(0x09&0x04)>>2=0 IN2 pin is low level.

This data field shows if this packet is generated by **Interrupt Pin** or not. [[Click here>>path:#Int_mod]] for the hardware and software set up. Note: The Internet Pin is a separate pin in the screw terminal.

**Example:**

09 (H) : (0x09&0x02)>>1=1 The level of the interrupt pin.

503

504

09 (H) : 0x09&0x01=1 0x00: Normal uplink packet.

505

506

0x01: Interrupt Uplink Packet.

11. Show Data in DataCake IoT Server

539

540

[[DATACAKE>>url:https://datacake.co/]] provides a human friendly interface to show the sensor data, once we have data in TTN, we can use [[DATACAKE>>url:https://datacake.co/]] to connect to TTN and see the data in DATACAKE. Below are the steps:

541

542

543

**Step 1**: Be sure that your device is programmed and properly connected to the network at this time.

544

545

**Step 2**: To configure the Application to forward data to DATACAKE you will need to add integration. To add the DATACAKE integration, perform the following steps:

546

547

1. Battery & how to replace

825

11. Battery Type

826

827

PS-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.

828

829

830

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

831

832

[[image:file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image031.png]]

833

834

835

Minimum Working Voltage for the PS-LB:

PS-LB: 2.45v ~~ 3.6v

1.

11. Replace Battery

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

844

845

And make sure the positive and negative pins match.

11. Power Consumption Analyze

851

852

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.

853

854

855

Instruction to use as below:

856

857

858

Step 1: Downlink the up-to-date DRAGINO_Battery_Life_Prediction_Table.xlsx from:

859

860

[[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/]]

861

862

863

Step 2: Open it and choose

* Product Model

* Uplink Interval

* Working Mode

And the Life expectation in difference case will be shown on the right.

111. Battery Note

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.

111. Replace the battery

898

899

You can change the battery in the PS-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.

900

901

902

The default battery pack of PS-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)
