Numeric sensor metadata.

Member Data Documentation

◆ accuracy

float sensors::NumericSensor::MetaData::accuracy

Sensor accuracy in percent.

How close in percent measurement is to actual value. This value has an implicit precision of 2, i.e. the double value must be rounded for 2 decimal digits before use. For example a reading of 10.0 and an accuracy of 0.2 means the actual reading value is 10.0 +/- 0.2%.

A value of 0 means unused.

◆ decdigits

int sensors::NumericSensor::MetaData::decdigits

Number of significant decimal digits.

Indicates how many digits should be displayed to the right of the decimal point. I.e. double values must be rounded with this precision.

◆ noiseThreshold

float sensors::NumericSensor::MetaData::noiseThreshold

Sensor noise threshold.

Threshold under which sensor measurements will be ignored. Sensor measurements below that value will be reported at the lower bound of the sensor range.

◆ range

Range sensors::NumericSensor::MetaData::range

Range of possible sensor readings.

Range values are rounded with with decimal digits.

◆ resolution

float sensors::NumericSensor::MetaData::resolution

Sensor resolution.

Minimum difference between any two measured values. Must be rounded with decimal digits.

◆ tolerance

float sensors::NumericSensor::MetaData::tolerance

Sensor tolerance.

Tolerance is given in +/- counts of the reading value. It indicates a constant magnitude possible error in the quantization of an analog input to the sensor. Rounded with decimal digits + 1.
