» Ag xtr 14: dendrometer sensor reading with reference

Basic example that turns on, reads and turn off the sensor. Measured parameters are stored in the corresponding class variables and printed by the serial monitor.

Required Materials

- 1 Waspmote Plug & Sense! Smart Agriculture Xtreme
- 1 dendrometer sensor

Notes

- This example is only valid for Waspmote v15

    ----------- [Ag_xtr_14] - Dendrometer sensor reading with reference --

    Explanation: Basic example that turns on, reads and turn off the
    sensor. Measured parameters are stored in the corresponding class
    variables and printed by the serial monitor.

    Measured parameters:
      - Trunk diameter
      - Stem diameter
      - Fruit diameter

  SELECT THE RIGHT SOCKET FOR EACH SENSOR.

  Possible sockets for this sensor are:
  - XTR_SOCKET_C           _________
                          |---------|
                          | A  B  C |
                          |_D__E__F_|


  Example: a 5TM sensor on socket A will be
  [Sensor Class] [Sensor Name] [Selected socket]
  Decagon_5TM    mySensor      (XTR_SOCKET_A);

  Refer to the technical guide for information about possible combinations.
