High accuracy detection & quantification of PM2.5
IAQ Sensor for PM2.5 detection
Detects PM2.5 that cannot be seen by the eye with a sensor.
It is commonly referred to as a dust sensor.
It outputs mass concentration (μg/m³) by high-precision
concentration conversion algorithm, then it's possible to visualize
IAQ (Indoor Air Quality).

Panasonic PM sensor introduction
What is PM2.5
PM2.5 is a general term for fine particulate matter
of 2.5 μm or less suspended in the atmosphere.
It's impossible to see with the naked eye, and easy to
penetrate deep into the respiratory tract. So, there are
concerns about the effects on the human body.

What is PM sensor
An optical sensor to visualize air quality that applies the phenomenon of scattering when light is applied to fine particles in the air
Features
Maintains long-term, high accuracy PM2.5 detection performance with a unique algorithm.
Maintain long-term performance by correcting parts whose performance deteriorates over time. Prevent wasteful operation of key components and extend their service life.
Maintenance-free by controlling stains
Intaking the air containing particulates into the sensor, however it's possible to control performance degradation by design of air flow structure so that the lens does not get dirty even after long-term use.
Contributing to the miniaturization of the equipment to be installed
37x27x12mm of compact size, then it contributes to the miniaturization of the equipment to be installed.
