Product Description:
YJJ OPC-N3 PM2.5 Air Particle Monitoring Sensor Is Used to Monitor
Heavily Polluted Environments
Features:
OPC - N3 is an optical particulate matter sensor launched by
Alphasense, a British company. As an upgraded version of OPC - N2,
it features multiple channels and a wide measurement range, making
it suitable for monitoring particulate matter in both indoor and
outdoor air quality and heavily polluted environments. Here are its
detailed specifications:
Core Measurement Parameters
Particle Size and Concentration: The spherical equivalent particle
size measurement range is 0.38 - 40μm, capable of accurately
detecting three key particulate matters: PM1, PM2.5, and PM10. The
maximum measurable concentration is up to 2000μg/m³, suitable for
heavily polluted scenarios, and it can also identify large-sized
particles such as pollen.
Classification and Counting: It has 24 software classification
channels, providing more detailed information on particle size and
shape compared to the 16 channels of its predecessor, which aids in
identifying pollution sources. The maximum particle counting rate
is 10,000 particles per second, with a coincidence probability of
only 0.84% at a concentration of 10⁶ particles per liter and 0.24%
at 500 particles per liter, ensuring high measurement accuracy.
Sampling Performance: The typical total flow rate is 1.2L/min, and
the typical sampling flow rate is 220mL/min. The histogram sampling
interval can be flexibly adjusted between 1 and 30 seconds.
Power Supply and Power Consumption
The power supply voltage range is 4.8 - 5.2VDC, suitable for common
DC power supply scenarios.
It has excellent power consumption performance, with a typical
current of 175mA in measurement mode and less than 50mA in standby
mode. The transient power consumption within 1ms after power-on is
less than 5000mW, demonstrating reasonable energy consumption
control.
Data and Interfaces
It is equipped with a SPI interface for real-time data transmission
and communication, and a Micro USB interface for firmware updates
and switching between independent working modes, meeting different
usage requirements.
It supports Micro - SD card data storage, with a maximum capacity
of 16GB. Data is saved in CSV format for easy export and analysis
later.
Environmental and Physical Parameters
The operating temperature range is -10℃ to 50℃, and the continuous
working humidity range is 0 - 95% RH (without condensation),
suitable for most indoor and outdoor environments.
The overall weight is less than 105g, and the appearance size is
the same as that of the previous OPC - N2, facilitating
replacement, upgrade, and integrated installation. The laser grade
of the sensor is 1, ensuring high safety during use.
OPC-N3 particle sensor is an optical particle counter based on the
principle of laser scattering, which supports detection of 24
particle size channels and is suitable for environmental
monitoring, meteorological stations, air quality assessment, and
other fields.
