the responses for which the post-processing has not been considered. The proposed correction scheme improves the fidelity of PM measurements by around two orders of magnitude w.r.t. The device and the method have been both demonstrated based on the data obtained during three measurement campaigns. The correction layer is derived from the sparse and non-uniform calibration data, i.e., a combination of the measurements from the PM monitoring station and the sensor obtained in the same location over a specified (relatively short) interval. Due to a limited accuracy of the PM detector, the measurement data are refined using a two-stage procedure that involves elimination of the non-physical signal spikes followed by a non-linear correction of the responses using a multiplicative surrogate model. In this work, a modular, mobile Internet of Things sensor for PM measurements has been proposed. Particulate matter (PM) measurement sensors belong to the key components that support operation of these systems. Its accurate and low-cost monitoring is important for developing services dedicated to reduce the exposure of living beings to the pollution.
