The present invention relates to a method and a device for performing PCO reaction. The method comprises steps of: guiding an air flow into a PCO reactor, which PCO reactor contains photocatalyst for the PCO reaction; splitting the air flow into a first stream and a second stream, wherein quantity of the first stream being less than quantity of the second stream; obtaining the humidity of the photocatalyst; controlling the humidity of the first stream according to the obtained humidity of the photocatalyst; adjusting the humidity of the photocatalyst by guiding the first stream to the photocatalyst; guiding the second stream through the photocatalyst; and illuminating the photocatalyst with light. By controlling the humidity of air passing through the photocatalyst oxidation based on the obtained humidity of the photocatalyst, PCO reaction can be performed effectively.

The invention proposes a method of controlling food temperature, the method comprising the steps of: heating food to a first target temperature; exciting a fluorescent marker of the food, wherein the fluorescent marker corresponds to a fluorophore of nutrient substance and/or anti-nutrient substance within the food; detecting current fluorescence-related parameter value of the fluorescence marker, and based on current heating time and predetermined relationships between heating time and fluorescence-related parameter value, calculating current reference fluorescence-related parameter value; comparing the detected current fluorescence-related parameter value with the calculated current reference fluorescence-related parameter value; and controlling heating power supplied to the food based on a comparison result.
摘要:
A pollen sensor comprising: a chamber (13) for housing an air sample having pollen to be identified; a UV light source (14) for providing excitation light to the chamber; a visible spectrum light detector (16) for detecting light which has been emitted by the pollen in response to the excitation light; and a controller (24) for analyzing the detected emitted light, wherein the controller is adapted to identify a pollen type based on the color spectrum of the received light. The pollen sensor analyzes fluorescent light from pollen particles, to identify the pollen type based on the color spectrum of received visible light, preferrably one or more ratios of light spectrum components. The invention is also directed to a pollen sensing method.
