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.
