Dust Sensing Technology
Reliable Sensor Technology
- Product reliability with a manufacturing standard
Based on the NIDS sensor semiconductor manufacturing standard,
stable mass production and miniaturization work have been activated.
This helps reduce system cost and size, and reduces manufacturing
time with standardized calibration systems.
- Ensuring accuracy by improving measurement precision
Deviating from amplification and digital interference in the field
of sensitive analog sensor signals, our technology provides strong and
precision-enhanced sensor measurement technology.
It ensures long-term stability benefits for users through improvement
research and development of analysis technology for parts prone to failure.
- Miniaturized sensor technology
The micro-sensor structure was developed through targeted
micro-system technology processing steps.In particular,
patented semiconductor chip production technology enables
the fusion of sensor analog and digital evaluation electronics.
Measurement principle of IR DUST SENSOR
The operating principle of the IR Dust Sensor is the optical scattering method.
Air enters through the sensor's intake valve, and an infrared LED light that switches repeatedly detects dust particles in the air.
Reliability and precision measurement
High and long-term stability
High accuracy IR dust SensorAccomplished more than
of technological innovation
For more than 20 years, NIDS engineers have been developing dust sensors
tailored to demanding markets and applications with unique technology.
Our technology prevents dust build-up on optical components and
provides long-term stability.
Measurement principle of Laser Particle Sensor
Pulse signal output by sensor is converted to a digital signal after the laser is scattered by particles.
Sensing the number and diameter of particles by analysis based on the correlation between signal waveform and particle diameter.
High Accuracy Laser Particle Sensor
NIDS' proprietary algorithm applies a new concept
to classify dust particles of any kind and size. Aerosols can
be accurately distinguished by improving measurement
of mass concentration, while sensing reliability has been
improved for precise measurement in a wide range
of environmental conditions.
Modern people spend 80-90% of their time in sealed indoor spaces.
Numerous micro pollutants in the air cause eye irritation, headache and fatigue, and have a direct impact on people's health.
NIDS believes that measuring indoor air quality and controlling within an appropriate range is the key to well-being and health,
and helps customers achieve maximum function when used in their products.
Ventilation and purification are the best options
for maintaining clean air.
Indoor air quality measurement data obtained from our sensors become our customers’ core asset
for configuring air purification systems or managing ventilation systems.
Outdoor air pollution enters indoor spaces through open window or ventilation systems. The indoor environment exposed to outdoor pollutants, such as soot, automobile exhaust gas, and pollen must be managed to ensure clean air quality. Therefore, the importance of particle sensing is ever-increasing. Comprehensive indoor air quality management for indoor environmental aggravating factors, such as paints, fabrics, cleaning products, food odors and dust mites, is a technology that should be actively considered at home.
In smart buildings, a system to monitor indoor air quality can be quickly and
easily installed and operated. Information providing remote control, wireless communication and APIs is used by the entire system to manage heating, ventilation and air conditioning (HVAC).
At the Workplace
Cluster infections during the COVID-19 pandemic provided real examples of how we need to manage and improve workplace air quality for the health of our employees. In general, improvement of indoor air quality can be expected by increasing the ventilation rate of offices, but employees can easily be exposed to harmful substances from printers or outdoor air pollutants, which are insufficient to apply to indoor structure, air quality, and in-house regulations. In addition to humidity and temperature, air pollutants, such as CO2, volatile organic compounds, and fine particles can affect work performance and well-being. Improvement of the office work environment through indoor air quality management technology leads to better decision-making among employees and lower rates of absenteeism, thereby boosting productivity.
Dangers in indoor air
Air pollutants, such as dust, mold, bacteria, and chemicals accumulate in enclosed spaces.
This is closely related to our lives as it negatively affects air quality in our homes and offices, causing health risks.
- Carbon dioxide
Carbon dioxide correlates with human activity
in enclosed spaces. High concentrations of carbon
dioxide can cause headaches, drowsiness, lethargy,
and performance degradation. Therefore, compliance
standards through sensors are recommended.
- Nitrogen dioxide
Nitrogen dioxide is produced by combustion of fossil
fuels and is present in emissions from factories and
automobiles. It acts as a precursor to ozone by reacting
with VOCs. Excessive exposure to nitrogen dioxide can
negatively affect the body, especially lung function.
Formaldehyde is widely used in production of industrial
products, such as adhesives in wood-based materials,
flooring or paints. It is also considered to be the main
cause of sick house syndrome. Exposure to high
concentrations above 50 ppm may cause eye irritation
and can lead to cancer.
- Volatile organic compounds
Volatile organic compounds are substances
containing carbon in the atmosphere. Short-term
exposure may cause irritation and dizziness, and
can exacerbate the symptoms of asthma. Long-term
exposure may cause lung cancer and damage to
the liver, kidneys and nervous system.
- Fine dust
Fine dust is generated not only from natural sources,
but also from various types of stationary or mobile
sources. It aggravates respiratory diseases, such as
asthma and triggers allergic reactions. Therefore, use of
a precision measuring system is required in accordance
with active management guidelines both
indoors and outdoors.
- Temperature and humidity
Control of temperature and humidity is an important
factor in achieving optimal environments for human life.
The human body feels most comfortable in the
humidity range of 40-60%, whereas dry air irritates
the respiratory tract and moist air creates
condensation, which can lead to mold.
