A city operates two types of air quality sensors: reference stations requiring professional calibration every 3 months, and lower-cost sensors requiring recalibration every 6 months. After one year, 6% of lower-cost sensors have drifted beyond acceptable accuracy between calibration visits. The city is considering reducing the lower-cost sensor recalibration interval from 6 months to 3 months. What trade-off does this decision involve?

Question

Accepted Answer

More frequent recalibration would improve data quality by catching drift earlier, but would approximately double the maintenance cost and effort for the lower-cost sensor fleet

Answer

More frequent recalibration is unnecessary because 6% drift rate is within acceptable limits for all regulatory purposes

Answer

More frequent recalibration would increase detection latency because sensors are offline during calibration

Answer

More frequent recalibration would reduce the lifespan of the sensors because the calibration process damages the sensing element
