Abstract
The invention discloses a fine particle sensor, comprising an infrared unit, dust holes and a photoelectric detection unit, wherein the fine particle sensor is characterized in that the infrared emission unit is connected to the dust holes, and the dust holes are connected to the photoelectric detection unit. The photoelectric detection unit comprises photoelectric detector and a signal conditioning circuit. The method, compared with a traditional method for detecting the fine particles, has a much higher efficiency. After a sensor module is manufactured, without knowing a concrete method for detecting the fine particles, a designer, only by means of provided the relation between parameters of the fine particles and output voltage, can directly apply the fine particle sensor on exploitation of equipment relative to the detection of the fine particles. The sensor module is convenient for using, and has a characteristic of small volume. When detecting the parameters of the fine particles, the fine particle sensor is not affected by air humidity.
Description
Technical field
The present invention relates to the fine particle technical field, relate in particular to a kind of fine particle sensor.
Background technology
When acquiring a certain degree, air pollution quality can bring threat to people's body and mind.And one of important parameter of estimating air quality is exactly fine particle, i.e. PM2.5.The method efficient that traditional on-site sampling analysis is detected fine particle is too low; It is heavy that the portable fine particle detector that has on the market now seems again, is inconvenient to carry, and the fine particle detecting unit is too huge to be to cause one of reason that whole detector seems heavy; In addition, be subject to the impact of air humidity during detection.There are problems in actual applications in present national standard method, apparatus expensive for example, and troublesome poeration, time-consuming (sampling time is long), effort etc., actual Supervision is difficult to accomplish.The at present domestic sensor that does not also have a kind of energy fast detecting fine particle parameter.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of fine particle sensor, use the scattering of light effect, can accurately test fast the fine particle parameter, and volume is very little, very easy to use, social benefit is high.
The present invention reaches goal of the invention by following technical solution:
A kind of fine particle sensor comprises infrared emission unit, and dust is by the hole, and photodetector unit is characterized in that infrared emission unit connects dust by the hole, and dust connects photodetector unit by the hole.
Described photodetector unit comprises photoelectric detector, signal conditioning circuit.
The advantage of the air quality remote monitoring system of the technical program is mainly reflected in:
1, wants high a lot of with respect to the method efficient of traditional detection fine particle.2, volume is little.3, make sensor assembly after, the personnel that design and develop do not need to be proficient in the concrete grammar that fine particle detects, only need to this fine particle sensor can be directly applied to the relevant device that the exploitation fine particle detects by the relation of the fine particle parameter that provides and output voltage, easy to use.When 4, this fine particle sensor detects the fine particle parameter, not affected by air humidity.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail.
Referring to Fig. 1, a kind of fine particle sensor comprises infrared emission unit, and dust is by the hole, and photodetector unit is characterized in that infrared emission unit connects dust by the hole, and dust connects photodetector unit by the hole.
Described photodetector unit comprises photoelectric detector, signal conditioning circuit.
In a word, the above only is preferred embodiment of the present invention, all equalizations of doing according to the present patent application claim change and modify, and all should belong to the covering scope of patent of the present invention.
