Embodiment
Below in conjunction with Fig. 1 to indoor air quality detecting device described in the utility model and comprise the system of this device, system comprises Detection of Air Quality device 10 and portable terminal 20, Detection of Air Quality device 10 is by the air quality situation in the sensor sensing chamber and demonstration, portable terminal 20 that also can the long-range user of being sent to satisfies the requirement that the user is known IAQ (indoor air quality) to inform the user.
Comprise pollutant sensor, environmental sensor, multimedia device and wireless transmission unit 108 in the Detection of Air Quality device 10, and the main control unit 100 that is connected with said apparatus.
Wherein, pollutant sensor comprises formaldehyde sensor 101, PM2.5 sensor 102 and/or CO
2Sensor 103.
Described formaldehyde sensor 101 is divided into electrochemical principle sensor and photoion principle sensor.
The detection principle of electrochemical principle detecting device is: the object gas molecule that contains formaldehyde is absorbed into the galvanochemistry sensitive electrode, through behind the dispersive medium, gas molecule generation electrochemical reaction under suitable sensitive electrode current potential, the electric current that above-mentioned reaction generation is directly proportional with gas concentration.
The detection principle of photoion principle sensor is: the photoion detector comprises a uviol lamp that is hidden under the special optical filtrator optical filtering, and the ionization potential of formaldehyde gas just can be given out light under the situation of 10.6eV.Thus, the object gas that contains formaldehyde enters sensor, and ionization potential is the radioactive ionization that sent by uviol lamp of the gas of 10.6ev and discharges free electron that these free electrons are obtained by high pressure, and produce the current signal of the concentration of formaldehyde gas.
PM2.5 sensor 102 is for detection of the content of airborne fine particle (Particulate Matter), and specifically, PM2.5 represents that particle diameter in every cubic metres of air is less than or equal to the content of 2.5 microns fine particle.
Described PM2.5 sensor 102 can be divided into trace vibration balance detecting sensor and Beta rays method/β rays method detecting sensor.
The detection principle of trace vibration balance detecting sensor is: use a vibration hollow conical pipe, at its vibration end filter membrane is set.When object gas passes through described filter membrane, fine particle wherein just is deposited on this filter membrane, filter membrane quality changes the variation that causes oscillation frequency, go out to be deposited on the quality of fine particle on the filter membrane by the oscillation frequency change calculations, calculate the concentration of fine particle again according to flow, indoor environment temperature and air pressure.
