A laser type particulate matter sensor is a device that uses a laser to measure the concentration of particulate matter in the air. The laser is directed through a chamber, and the amount of light that is scattered by the particles is measured. This information is then used to calculate the concentration of particulate matter in the air.
Laser type particulate matter sensors are used in a variety of applications, including: Air quality monitoring Industrial hygiene Research Consumer products, such as air purifiers Laser type particulate matter sensors are a relatively new technology, but they have already been shown to be accurate and reliable. They are also relatively easy to use and maintain.
Advantages of laser type particulate matter sensors include: High accuracy Low maintenance Easy to use Can be used in a variety of applications Disadvantages of laser type particulate matter sensors include: Can be expensive May not be suitable for all applications May require calibration Overall, laser type particulate matter sensors are a valuable tool for measuring air quality.
They are accurate, reliable, and easy to use. Here are some additional information about laser type particulate matter sensors: They can measure the concentration of particulate matter in the air in real time. They can be used to measure the concentration of different types of particulate matter, including PM10, PM2.5, and ultrafine particles.
They can be used to measure the concentration of particulate matter in both indoor and outdoor air. They can be used to monitor air quality in a variety of settings, including homes, schools, offices, and factories.
They can be used to track changes in air quality over time. They can be used to identify sources of air pollution. They can be used to evaluate the effectiveness of air pollution control measures.
The Global Laser Type Particulate Matter Sensor Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Mitsubishi Electric Corporation (TOKYO: 6503) today announced the development of a tiny, high-precision air-quality sensor, the world’s first to detect all fine particles measuring less than 2.5 micrometers in diameter, known as PM2.5, as well as pollen and dust. It can also precisely detect particle density.
Scattered light from PM2.5 particles is detected using a unique double-sided mirror design developed by Mitsubishi Electric, which gathers about 1.8 times more scattered light than typical single-sided versions. An air flow controller ensures consistent airflow.
Components were meticulously placed to prevent impeding airflow and laser beams and were appropriately engineered to create a tiny form factor. The initial shape-discrimination algorithm developed by Mitsubishi Electric distinguishes between pollen and dust based on variations in the optical properties of their scattered light.
A laser diode, aspheric lens, light-collecting mirror, photodetector, and airflow controller comprise the air-quality sensor prototype. The prototype is 67mm (W) x 49mm (D) x 35mm (H) in size. A detectable particle has a minimum size of 0.3 micrometer.
PM2.5 has been a severe issue in nations such as China, India, and Japan, creating air pollution and health problems. This trend has heightened public concern and generated demand for high-precision air-quality sensors capable of detecting PM2.5.
However, high-precision PM2.5 sensors are still bulky and costly, restricting their applications to commercial use mainly.
