Abstract
The utility model discloses a personal PM2.5 sensor, including base and gas circuit, sensor upper cover, circuit board, laser instrument, photoelectric sensor, laser mounting, fan and battery, the circuit board is installed at sensor upper cover lower extreme, battery and fan stay in the cavity of establishing on one side of installing in base and gas circuit, laser instrument and photoelectric sensor set up in the laser mounting, just the laser mounting install in base and gas circuit insole seat side cavity, this personal PM2.5 sensor has the PM2.5 detecting instrument that bluetooth function can connect with the cell -phone, has adopted miniature fan to make the air current carry out quick compulsory convection, when the dust moves the light beam that laser caught, takes place the scattering, measures the size and the concentration of particle through detecting the scattering, and both the cost is reduced had the measurement that has realized the high accuracy. Have characteristics such as miniaturized simultaneously through the optimal design.
Description
Technical field
The utility model relates to sensor application technical field, and especially a kind of PM2.5 with oneself passesSensor.
Background technology
With the raising along with people life style, environmental pollution is also more and more serious, especiallyPM2.5, but existing PM2.5 and detection of particles instrument cost are all very high, for realityInspection to PM2.5 in existing own family, one cheaply PM2.5 detector be essential, existing dust sensor can replace measurement, but it adopts infrared mode, measures powderDirt is by the displacement of dust, interference free performance a little less than, in this simultaneously, sensor also existsNull offset is larger, and reflecting time is less etc.
Therefore, designing a kind of sensor of new structure and then make up the deficiencies in the prior art is peopleThe technical issues that need to address.
Utility model content
Prior art is difficult to meet people's productive life needs, in order to solve asking of above-mentioned existenceTopic, the utility model proposes a kind of PM2.5 sensor with oneself.
For realizing this technical purpose, the technical solution adopted in the utility model is: with oneself a kind ofPM2.5 sensor, comprises base and gas circuit, sensor upper cover, circuit board, laser instrument, lightElectric transducer, laser fixture, fan and battery; Described circuit board is arranged on sensor upper coverLower end; Described battery and fan are arranged on a side in base and gas circuit and stay in the cavity of establishing; DescribedLaser instrument and photoelectric sensor are arranged in laser fixture, and described laser fixture is installedIn base and gas circuit in base side cavity; Described fan, laser instrument, photoelectric sensor andCircuit board is electrically connected; Battery and circuit board are electrically connected.
Further, on described circuit board, offer the hole corresponding with fan.
Further, the base in described base and gas circuit and sensor upper cover form outside sensorShell.
Further, can also be connected with mobile phone by bluetooth, can view by mobile phone A PPData, and can upload the data to high in the clouds; Described APP can obtain the address of mobile phoneInformation, and whether judgement has national PM2.5 measuring station around according to address information, if depositedJust can calibrate PM2.5 at measuring station.
Compared with prior art, the utlity model has following beneficial effect: this carry-on PM2.5Sensor, have that Bluetooth function can be connected with mobile phone PM2.5 detecting instrument, the designAlso adopted mini-fan to make air-flow carry out quick forced convertion, dust moves to laser and getsLight beam time, there is scattering, measure size and the concentration of particle by detecting scattering, bothReduce cost and realized high-precision measurement; There is miniaturization etc. through optimal design simultaneouslyFeature. Can carry, realize and measure PM2.5 everywhere.
