precision range.
An object of this type SHOULD be defined together with
objects of type EntitySensorDataType and
EntitySensorDataScale. Together, associated objects of
these three types are used to identify the semantics of an
object of type EntitySensorValue.
If an object of this type contains a value in the range 1 to
9, it represents the number of decimal places in the
fractional part of an associated EntitySensorValue fixed-
point number.
If an object of this type contains a value in the range -8
to -1, it represents the number of accurate digits in the
associated EntitySensorValue fixed-point number.
The value zero indicates the associated EntitySensorValue
object is not a fixed-point number.
Agent implementors must choose a value for the associated
EntitySensorPrecision object so that the precision and
accuracy of the associated EntitySensorValue object is
correctly indicated.
For example, a physical entity representing a temperature
sensor that can measure 0 degrees to 100 degrees C in 0.1
degree increments, +/- 0.05 degrees, would have an
EntitySensorPrecision value of '1', an EntitySensorDataScale
value of 'units(9)', and an EntitySensorValue ranging from
'0' to '1000'. The EntitySensorValue would be interpreted
as 'degrees C * 10'.";

value.
An object of this type SHOULD be defined together with
objects of type EntitySensorDataType, EntitySensorDataScale
and EntitySensorPrecision. Together, associated objects of
those three types are used to identify the semantics of an
object of this data type.
The semantics of an object using this data type are
determined by the value of the associated
EntitySensorDataType object.
If the associated EntitySensorDataType object is equal to
'voltsAC(3)', 'voltsDC(4)', 'amperes(5)', 'watts(6),
'hertz(7)', 'celsius(8)', or 'cmm(11)', then an object of
this type MUST contain a fixed point number ranging from
-999,999,999 to +999,999,999. The value -1000000000
indicates an underflow error. The value +1000000000
indicates an overflow error. The EntitySensorPrecision
indicates how many fractional digits are represented in the
associated EntitySensorValue object.
If the associated EntitySensorDataType object is equal to
'percentRH(9)', then an object of this type MUST contain a
number ranging from 0 to 100.
If the associated EntitySensorDataType object is equal to
'rpm(10)', then an object of this type MUST contain a number
ranging from -999,999,999 to +999,999,999.
If the associated EntitySensorDataType object is equal to

either the value 'true(1)' or the value 'false(2)'.
If the associated EntitySensorDataType object is equal to
