Air Quality Meters PMS7003. PM2.5 Sensor Module Built-in Fan.

Principle: this sensor uses the principle of La-Ser scattering, i.e. the La-Ser is irradiated to suspended particles in the air to create scattering, and at the same time the scattered light is collected at a certain angle to maintain the curve of the scattered light over time.

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.

0 error alarm rate, real-time response and support for continuous detection, particle size with minimum resolution 0.3um. You can use the sensor safely.

The sensor is omnidirectionally shielded on six sides and has a strong anti-interference performance as well as an optional direction of the air inlet and outlet.

For a wide range of applications, users no longer need to design the ultra-thin air duct design (only 12 mm), which is suitable for portable devices. A good choice for you.
