Definition of a sensor: A device with a single id, name, lat / long, and depth. Must have at least one reading parameter, but may have several. Optionally has a brand and model.

...

Validation should be performed at least via the API and potentially through the UI as well.

Architecture

Please take this as guidance rather than instruction. The following tables seem to make sense to allow users to document sensors and to integrate them with those external services.

• Sensor: The attributes describing the physical device and it’s location. This should somehow tie to a point location for that sensor.

• sensor_parameter: The parameters that instruct LiteFarm on how to parse data read by the sensor but don’t change from reading to reading and also aren’t related to the physical nature of the sensor. May just be part of the sensor table!

• sensor_reading: Readings from the sensor.

• integration: A table documenting

...

Questions:

What are the valid types of sensor (reading) types to start with?

• soil_moisture_content

• water_potential

• temperature

How do we link up sensor_reading_types with a depth via csv upload?

Each sensor will only have 1 depth. We may choose to display sensors with very similar lat / long and different depths as the same sensor via the UI - but they are different in terms of sensor reading types and readings.

How does ensemble tie a reading to a parameter when posting new sensor readings?

It appears to be based on “parameter_number”. Need to explore what exactly this means to ESCI.

• Create webhook for organization

  • Will send a confirmation request in the form of an empty array to the url (with authorization if any) before being created

• Webhooks automatically send any organization data between current time and the webhook's last transmit time based on the webhook's frequency as long as it is active. Will send an empty array if no new data

• authorization_header is optional

• frequency is in minutes

• Errors

  • 400_BAD_REQUEST

    • Invalid json, incorrect url

    • received Response other than 200_OK from url during creation

    • Errors when trying to send confirmation request to the url

• Adds device to cloud with the specified POST data:

  • part_number

  • hardware_version

  • Device ESID will automatically be generated and any device parameters will be created based on the DeviceType's default parameter list if it exists.

  • Any generated parameters will have a 1:1 calibration generated with it as well

  • If device is interfacer, sets configurable to TRUE, so users can modify the device with other APIs

  • Errors:

    • 400_BAD_REQUEST

      • Device type with part_number does not exist

      • Any fields missing

  • Only ESci admins can call

What depths are the sensors at (for this project)?

10, 20, 30, and 50cm. Duplicates at 10 and 30.
