PMS7003 PMS7003M PMS5003 Digital universal particle concentration
sensor
PMS7003:
Main characteristics:
Zero false alarm rate
Real-time response
Correct data
Minimum distinguishable particle diameter :0.3 micrometer
High anti-interference performance because of the patent structure
of six sides shielding
Optional direction of air inlet and outlet in order to adapt the
different design
Very Slim
Overview:
PMS7003 is a kind of digital and universal particle concentration
sensor, which can be used to obtain the number of suspended
particles in the air, i.e. the concentration of particles, and
output them in the form of digital interface. This sensor can be
inserted into variable instruments related to the concentration of
suspended particles in the air or other environmental improvement
equipments to provide correct concentration data in time.
Working principle:
Laser scattering principle is used for such sensor, i.e. produce
scattering by using laser to radiate suspending particles in the
air, then collect scattering light in a certain degree, and finally
obtain the curve of scattering light change with time. In the end,
equivalent particle diameter and the number of particles with
different diameter per unit volume can be calculated by
microprocessor based on MIE theory. Please find the functional
diagram of each part of sensor from Figure 1 as follows.
