I. Product introduction:
AQM-09 is a new product which can monitor the air quality via the value of O3,
SO2, NO2, CO, PM2.5, PM10, etc. The target value is converted into voltage
signal by operational amplifier circuit, and then filtered through high-precision
AD data acquisition system. Finally, the gas concentration is calculated by CPU.
Particulates mainly use laser scattering method to produce different scattering
light according to different particle diameters under laser scattering conditions.
The scattered light intensity is collected by a response device, and the particle
4
concentration is obtained after amplification, filtering and AD acquisition. The
obtained gas concentration and particulate matter concentration can be displayed
on LCD screen in real time, and can also be transmitted to cloud platform or
environmental protection platform through GPRS, 4G LTE and other network
signals, so as to realize the monitoring of regional environmental quality.

III. Function introduction
Cyclone type physical cutter
The particle concentration was measured by laser scattering. The test sample of
the air in the atmosphere is pumped to the sensor assembly with a precision flow
controlled membrane pump. The sensor measurement module is based on Gustav
Mie particle light scattering theory and combined with Micro-Photoelectric
detection technology to produce a complete set of air particle distribution
concentration measurement system.
10
The system ingeniously designs the light sensitive area as the place where the
scattering of particles occurs. When the particles pass through the light sensitive
area formed by the focused laser, the light scattered by particles is collected by the
Micro-Photoelectric detector on the detection window. The Micro-Photoelectric
detector quickly and accurately converts the received light intensity signal into the
equal voltage signal, and the signal is dense. Degree corresponds to the unit
concentration value of particles. After coefficient conversion, the dust
concentration value is output in real time through data interface. With cyclone
physical cutter and PID real-time temperature control system, the response of
humidity to test results can be effectively reduced. Combined with sheath gas
protection system, the influence of test samples on optical elements is effectively
prevented.
