PM-G7 PM2.5 DUST SENSOR compatible PMS7003

Laser PM2.5 DUST SENSOR  PM-G7 Thin shape Laser digital PM2.5 sensor (Inculd transfer board + cable)

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

PM-G7 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.
