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.
- Document about 「the fine particulate matter (PM2.5)」from Osaka Prefectural Department of Environment
- Self servey data about hair
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.
Multiple air quality detection
IAQ Sensor for Multiple detection NEW
Detects TVOC, eCO2, Temperature and Humidity in addition to
particulates (PM1.0, PM2.5 and PM10 ) in the air.
Various types of IAQ (Indoor Air Quality) can be visualized.
What's TVOC
TVOC (Total Volatile Organic Compounds) is a general term of VOC. VOC (Volatile Organic Compounds) is an abbreviation for organic compounds that are highly volatile and become gases in the atmosphere.
What's eCO2
eCO2 means the equivalent value of the concentration of CO2 estimated from TVOC.*
- It does not measure CO2 itself
Features
TVOC, eCO2, Temperature and Humidity detection with small size
5 types of indoor air quality such as PM2.5 and TVOC can be measured and compact size (37x37x12mm) is achieved by miniaturizing the optical part.
TVOC (Total Volatile Organic Compounds)
eCO2 (estimated concentration of CO2)
Detects volatile organic compounds and measures indoor air quality. Calculate CO2 concentration from VOC emitted from the human body. Output the level values apply to IAQ standards on Federal Environment Agency of Germany (UBA).
Temperature and Humidity
Improvement of measurement stability and response is achieved by establishment protective layer on the sensor element of temperature and humidity detection.
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.
Useful for simple communication and easy integration layout
In case of using a sensor for individual detection
In case of using a sensor for multiple detection

[Precautions for Use]
If activated in an environment exceeding IAQ Level 1, a temporary offset may occur in the readings.
The offset will be cleared once clean air at IAQ Level 1 is detected. - IAQ values and eCO2 characteristics after pre-powering for 48 hours in clean air.
- The accuracy of eCO2, temperature, and humidity is for reference only.
- Designed life under normal operating condition(continuous operation) under room temp. at 25℃, humidity 60% or less.
- This product may generate noise depending on the method of its installation.
