# Linear sensor calibration
# Scope: Two-point linear calibration mapping sensor reading to length.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

reading = 2 V
zeroReading = 0.5 V
spanReading = 4.5 V
span = 100 mm

position := (reading-zeroReading)*span/(spanReading-zeroReading) [mm]

check reading within calibration: reading >= zeroReading
check reading upper bound: reading <= spanReading

scenario alternative: reading = 1.6 V
