What is a Particle sensor?

A particle sensor is a device used to measure airborne particulate matter, including fine particles such as PM2.5 and PM10, as well as pollen, smoke, dust, and microorganisms. These sensors employ technologies like laser light scattering and electrical resistance to quantify particle concentration and size, providing real-time data on air quality.

Particle sensors have various applications, including environmental monitoring, indoor air quality management, and emission control in industrial facilities and power plants. For example, using particle sensors to monitor air pollution in urban areas helps assess health impacts and implement appropriate measures. In indoor environments, particle sensors can detect high concentrations of fine particles, prompting actions such as improving ventilation or replacing filters. The introduction of particle sensors is expected to contribute significantly to maintaining clean environments and promoting health management.

Application of Particle sensor

Here are some specific examples of particle sensor usage:
１．Urban Air Quality Monitoring
In many cities, air pollution is a serious issue due to traffic and industrial activities. By installing particle sensors to monitor PM2.5 and PM10 levels in real time, authorities can assess pollution levels and implement necessary measures. For instance, when pollution spikes, alerts can be sent to residents, or campaigns can be launched to promote public transportation usage.
２．Emission Monitoring in Industrial Facilities
Factories and manufacturing plants often generate dust and smoke, requiring compliance with environmental regulations. By utilizing particle sensors, the concentration of fine particles in emissions can be measured to ensure they remain within regulatory limits. This also helps in improving production processes and optimizing equipment.
３．Indoor Air Quality Management
In office buildings and homes, particle sensors can be installed to monitor indoor dust and pollen levels. This is particularly important for individuals with allergies, as particle concentration significantly affects their health. If the sensors detect high particle levels, alerts can be issued to encourage ventilation, helping to maintain a comfortable indoor environment.
４．Health Monitoring and Research
Healthcare and research institutions use particle sensors to assess environmental conditions for patients or research subjects. For example, in the treatment of asthma patients, measuring the concentration of fine particles in their surroundings can help analyze how environmental factors impact their symptoms.
５．Agricultural Monitoring
In agriculture, particle sensors are employed to monitor pollen and pathogens. This helps predict crop health and pest outbreaks, aiding farmers in determining the optimal timing for pesticide application.
