1, range
Measuring range of the sensor: the maximum value and the minimum measured value measured.
For example, when a measurement range of 0 ~ 250kpa pressure transmitter, we actually measured when a pressure of 60kPa, we should choose the range 0 ~ 100kpa, this range is the range used.
2, error and accuracy
In engineering, using a module or sensor, we will first discuss its accuracy or error.
For example, using a GPS module, the positioning accuracy must be considered; using some analog output, will consider the accuracy of the ADC and the like.
I understand: in the process of communication, error and accuracy can be equated.
In discussing the precision or error of a sensor, it is discussed relative error or absolute error.
Relative error: (measured value - reference value) / (upper - lower)
Absolute Error: measurement - standard value
GPS accuracy discuss the general discussion is absolute error.
3. Resolution
10, for example, a ruler out, minimum scale of 1mm, the resolution of 1mm.
3, the sensitivity
