What Would You Do With a Sensor Reading That Carried Its Own Error Bar?
Every calibrated instrument is a little wrong. It does not say by how much. The correction figures stored inside it are rounded to fit the memory available. The reading comes out as though they were exact. On one thermal camera, a Melexis MLX90640, the error that hides there averages 0.44 °C and reaches 5.35 °C at the worst of its 322,560 measured output distributions. UxHw® carries that error through the same conversion the instrument already runs, in one pass. Enter your instrumented points, your reading rate, and your reject volume.

Signaloid Moduleη is the fidelity setting, the detail the processor keeps in each distribution. Higher is more faithful and slower. Every module has a ceiling. The published thermal figure was measured on the two microSD parts. C0-SD is included because it is the only one that will displace a working storage card.
Where the Uncertainty Comes FromThe published work quantifies the first: a sensor stores its calibration coefficients rounded to fit its EEPROM. The compensation routine then reports a temperature as though they were exact.
Cost of a False RejectWhat one wrongly rejected part or spurious alarm costs you. The default follows the plant you picked. It is the figure the whole false-alarm case depends on, so set your own.
Rejects Per Day TodayHow many rejects or alarms the line raises now. Combined with the published precision improvement, this is what sizes the saving.
Override the speedup
This calculator's figures rest on one measured multiple, cited
with its baseline under the result. If you have measured your own, on your own workload, enter it
here and the arithmetic follows it. Nothing leaves the page. The citation under the figures still
reports what Signaloid measured, a banner above the result says the numbers are yours, and the
exported card and the quote mail both record the substitution. Clear the field to go back.
There is no single multiple to override here. This
calculator's figures rest on several separately measured quantities rather than on one speedup.
Each is cited with its own baseline under the result. Overriding one of them alone would give
a figure that follows from no measurement, so the field the other calculators carry is absent.
