Voici dashboard: sensor calibration

modified2026-06-08statusfinished

An example Voici dashboard¹1Voici compiles a notebook to a static, serverless dashboard — here mocked as a static page rather than an actual notebook export, since this pipeline has no Jupyter kernel to run against. — a notebook rendered as a standalone app, restyled with the grokkingstuff Voilà/Voici theme instead of JupyterLab's default light chrome.

Bench 03 — sensor calibration

Fits a linear calibration curve from raw ADC counts to pressure (kPa). Adjust the sample count and re-run to see the fit tighten.

Inputs

import numpy as np
samples = 240  # widget-controlled below
raw, kpa = load_calibration_run(samples)
fit_linear(raw, kpa)

Output

slope=0.0847 kPa/ct, intercept=-12.30 kPa, R²=0.9962
