The limitations of low-cost sensors
Drift, cross-sensitivity and calibration: where compact devices may help and where stronger evidence is needed.
Convenience and constraint
Compact sensors can make broader coverage possible, but readings may be affected by drift, environmental conditions and interference from other substances.
Fit for purpose
The right question is not whether a device is low cost, but whether its performance, quality controls and maintenance are suitable for the intended decision.
