How to add an offset to a sensor reading.


Due to a variety of reasons it is sometimes necessary to add an offset to the value obtained from a sensor to achieve the required accuracy. For example, a temperature sensor may be reading off by 0.5 degree as compared to a calibrated high accuracy temperature measuring device used as a standard.

Add an algorithm in the conversion field of the input objects to adjust the value by the necessary offset.

In the example here the conversion entered could be:

Elecvalue + 0.5

or Elecvalue + TempSensorOffset where TempSensorOffset is an InfinityNumeric point that has been set to the amount of offset to apply. 

While this example uses a very simple conversion algorithm, the input’s conversion can be thought of as a one line PE program that can use PE system functions.

Elecvalue + Maximum(TempSensorOffset, 1.5)
