PM25 DUST SENSOR PMS7003 / G7 Thin Shape Digital PM25 Sensor (Inculd Transfer Board + Cable)

Wide range of applications, users no longer need to design the air duct ultra-thin design, only 12 mm, suitable for portable devices. This sensor uses the principle of scattering, that is, is irradiated on suspended particles in the air to produce scattering, and at the same time, the scattered light is collected at a specific angle to obtain the curve of the scattered light with time. Furthermore, the microprocessor uses an algorithm based on the MIE theories to obtain the equivalent particle size of the particles and the number of particles of different sizes per unit volume. Sixsided omnidirectional shielding, strong antiinterference performance. 0 error alarm rate, realtime response and support for continuous acquisition, minimum resolution particle size 0.3um. Adapter board and cable color random, don't accept the specified color.
