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 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.

Abstract: A particle sensing device, configured to detect a particulate concentration in a fluid, includes a detecting channel, a sensing space, a light source and a sensor. The detecting channel is configured for the fluid to flow therethrough. The sensing space is located on one side of the detecting channel and connected to the detecting channel, and the sensing space is surrounded by a surrounding wall. The light source and the sensing space are located on opposite sides of the detecting channel, and the light source is configured to emit light towards the detecting channel. The light is configured to hit at least one particle in the fluid. The sensor is disposed on an inner surface of the surrounding wall, and the sensor is configured to detect a scattered light energy generated when the light hits the particle. The sensor is a distance apart from the detecting channel.
