PMS5003S is a multifunction sensor that can detect not only the
concentration of particles and formaldehyde but also the value of
temperature and humidity. As the particle concentration sensor it can be
used to obtain the number of suspended particles in the air by laser. It
also integrates in it an electrochemical probe for formaldehyde .The
sensor can be inserted into variable instruments related to the environment
parameters in the air or other environmental improvement equipments to
provide correct data in time.
