Abstract

Formaldehyde electrochemical sensors are arranged on side walls, ceilings, etc, which can't effectively reflect the concentration level of formaldehyde, so the ventilation system can't respond in time or respond too fast, resulting in the ineffective removal. In this study, we set up an experimental room to monitor the formaldehyde in different locations under different working conditions, then linearly fit the detected concentration to the target concentration. With the same working conditions' average correction coefficients, correcting the actual point monitoring data. The results show that the average error of the monitoring data after the correction is reduced by 46-71%. This method is easy to operate and has certain reference significance for the sensor setting in actual engineering.
