» Ag xtr 24: Datasol Met sensor reading

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 Solar radiation and temperature Datasol Met probe

Notes

- This example is only valid for Waspmote v15

    ----------- [Ag_xtr_24] - Datasol Met sensor reading ------------------

    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:
      - Measured radiation
      - Semi-cell 1 radiation
      - Semi-cell 2 radiation
      - Environment temperature
      - Panel temperature
      - Peak sun hours
      - Necessary cleaning notice
      - Wind speed

  SELECT THE RIGHT SOCKET FOR EACH SENSOR.

  Possible sockets for this sensor is:
  - XTR_SOCKET_E       _________

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