Sensors

Optional sensors:

• Temperature sensor
• Death detector
• Magnetic switch
• Activity or position detector:
  
  CLASS I    Position detector.
                     This detector enables you to know wich one of two possible positions of the animal thanks to
                    different rates for each position. It can also be used as an activity detector in slow-moving
                    animals.

                             SHORTCOMINGS: The overall battery life-time is considerably reduced, because one
                             of the rates is much more quick than necessary, in order for us to be able to discriminate
                             it from the slower one.
        
         CLASS II    By using just one rate according to the kind of animal, you can get occasional variations
                              which determine the activity of the animal.

                              ADVANTAGES: the battery life-time can be considerably higher than that of the previous
                              class, and it can be used with quicker animals.

         CLASS III  Taking an adequate rate for the kind of animal, this rate is removed and superseded by the
                             rate of the movement of the animal, until it no longer moves.
                             ADVANTAGES: It can reproduce the activity with great accuracy. Therefore it can be
                             used as a death detector.
