SensorValue
For sensors that measure voltsAC, voltsDC, amperes, watts, hertz, celsius, cmm this item is a fixed point number ranging from -999,999,999 to +999,999,999. Use the value -1000000000 to indicate underflow. Use the value +1000000000 to indicate overflow. Use SensorPrecision to indicate how many fractional digits the SensorValue has. For sensors that measure percentRH, this item is a number ranging from 0 to 100. For sensors that measure rpm, this item can take only nonnegative values, 0..999999999. For sensors of type truthvalue, this item can take only two values: true(1), false(2). For sensors of type specialEnum, this item can take any value in the range (-1000000000..1000000000), but the meaning of each value is specific to the sensor. For sensors of type other and unknown, this item can take any value in the range (-1000000000..1000000000), but the meaning of the values are specific to the sensor. Use Entity-MIB entPhysicalTable.entPhysicalVendorType to learn about the sensor type.
