Explanation: As the trigger, ECOTEL records
the two event types "Measured value moves
beyond limit" and "Measured value returns to
this side of threshold". They are always
recorded in alternation and never the same type
twice in succession.
This prevents small fluctuations about the limit
from generating continuous SMS events.
Example: The input signal corresponds to a
temperature to be monitored. The two event
types are then interpreted as follows:
"Temperature too high " and "Temperature back
to normal".
