SenseCap S210X is a powerfull line of sensors with built-in Bluetooth and LoRaWAN interface, specially meant for outdoors applications such as agriculture, smart cities, among many others. This series is composed by the following devices:

The procedure specified here works the same for all of the 5 devices compromising the S210X series.

Requirements:

  • Any of Seeed Studio’s SenseCap S210X Series

  • An active account on Helium Console

  • An active account on Ubidots

  • A cellphone running either Android or iOS with Bluetooth

1. Configure the SenseCap S210X

  • Install the SenseCAP mobile application by searching “SenseCAP Mate” on your device’s application store or by scanning the following QR code:

  • Turn on your cellphone’s Bluetooth and then turn on the SenseCap by pressing and holding the config button for 3 seconds:

  • Open the SenseCAP on your mobile device and, there, select S210X Sensor, then tap on Setup

  • Select your device by tapping on it:

The following settings depend on your region, e.g. if you are located on Europe you should select EU_863, if you are located on India, you should choose IN_865. In the following link you can find out more about each country allowed band and it's regulations. This guide was developed using AUS_915 band, however, remember to change these settings according to your region.

  • Tap on the “Settings” tab and edit the following settings:

    • Platform: Helum

    • Frequency Plan: AUS915

    • Uplink Interval (optional): 5

  • Copy the following values (do not modify any). We'll use them later:

    • Device EUI

    • APP EUI

    • APP Key

  • Click on “Send”

2. Register the SenseCap S210X on Helium LNS

  • Log into your Helium console.

  • Go to “Devices” section

  • Click on “Add device” button

  • Give your device a meaningful name

  • Set the device's data such as "DevEui", "AppEui", etc.

  • Give your device a label in case you are setting up several devices of the same kind

  • Click the "Save Device" button

3. Create the Integration to Ubidots

  • Go to "Integrations" section

  • Click on "Add integration"

  • Search for the Ubidots integration among the list of partners and click on it

  • Click on "+ Add integration"

  • Enter your Ubidots Token and click "Get Webhook URL" button

  • Wait for "Obtained Ubidots Webhook URL!" message and click the "Continue" button

  • Set a name for your integration

  • Click "Add Integration"

4. Configure the decoder function

  • Go to "Functions" section

  • Click on "Create new function" button

  • Click "Custom"

  • Set a name for your decoder function

  • Delete all the code in the textbox

  • Paste the following code

  • Click on "Save Function" button

Decoder function code:

This decoder is provided and supported officially by Seeed Studio, solely for Helium LNS at the following link. Please refer to the link provided in order to obtain the most updated decoder for your application.

5. Connect the Integration to Ubidots

  • Go to "Flows" section

  • Search for your device in the "Devices" section in the drop-down menu and drag it to the blank area

  • In the same drop-down menu, change the tab to "Function" and search for the function created in the previous step, hold click and drag it to the blank area

  • Do the same as above, instead, this time search for the integration created at step 3. Hold click and drag it to the blank area.

  • Connect the dots as the following GIF shows

6. Configure the Ubidots decoder

  • Go to your Ubidots account

  • Go to "Devices" --> "Plugins"

  • Search for a newly created plugin. Its name is most likely to be "Helium integration"

  • Click on the pencil icon

  • Head to the "Decoder" section at the left side of the screen

  • Scroll down to the "Decoding Function" section and delete all the code present in the textbox

  • Paste the following code

  • Click on "SAVE & MAKE LIVE" button to save the changes

Decoder function code:

 def format_payload(args):

payload = args["decoded"]["payload"]
ubidots_payload = {data["field"]:data["value"] for data in args["decoded"]["payload"]}
print(args)
