Abstract: A method of building upstream-and-downstream configuration of sensors includes determining two sets of geographic position data of a target sensor and a candidate sensor, obtaining pollution-associated periods according to pieces of flow field data, the sets of geographic position data and pieces of target sensing data of the target sensor to determine a pollution-associated period, calculating a correlation between target sensing data obtained by the target sensor during the pollution-associated period and candidate sensing data obtained by the candidate sensor during the associated air pollution period to obtain sensor correlations, and determining the target sensor and the candidate sensor having a upstream-and-downstream relationship with the candidate sensor being used as a satellite sensor of the target sensor when a quantity ratio of sensor correlations being larger than or equal to a correlation threshold is larger than or equal to a default ratio.

Abstract: A fluid quality tracing method includes obtaining pieces of fluid concentration distribution data of a detected region corresponding to detection time points respectively, generating pieces of concentration grid data respectively according to the pieces of fluid concentration distribution data, obtaining pieces of fluid moving data of the detected region corresponding to the detection time points respectively, obtaining estimated positions according to the fluid moving data and an initial position, and creating a fluid concentration trajectory according to the pieces of concentration grid data, the initial position and the estimated positions. The initial position and the estimated positions are located in the detected region. The fluid concentration trajectory includes line segments with terminals corresponding to the initial position and the estimated positions respectively, and the line segments indicate concentration representative values respectively.

Abstract: A light-emitting device with a sensing function is provided. The light-emitting device includes a substrate, a first light-emitting-diode die, and a first photosensitive element. The first light-emitting-diode die is disposed on the substrate and includes a main light-emitting top surface and a side light-emitting surface surrounding the main light-emitting top surface. The first photosensitive element is disposed on the substrate and includes a photosensitive surface. The photosensitive surface is parallel to the main light-emitting top surface. A distance between the main light-emitting top surface and the substrate is greater than a distance between the photosensitive surface and the substrate distance.
