Ag_xtr_05 - SQ-110 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.

Measured parameters:

• Photosynthetically active radiation (PAR)

• Sensor voltage

  SELECT THE RIGHT SOCKET FOR EACH SENSOR.

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


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