APM2000 Laser Air PM2.5 Sensor Module Dust Particle Sensor For Air Quality Monitoring Equipment

Product Introduction:

APM2000 is a digital particulate matter detection sensor designed based on the laser scattering principle, which can detect particulate matter concentration in real - time. It has the characteristics of high - precision measurement, good stability, small size and easy integration.

Working Principle

APM2000 contains a laser emission element and a light - detection element, which are placed inside the casing in a cross - shaped manner. When air flows through the sensor cavity, the particulate matter in the cavity air causes laser scattering, and the light - detection element collects the change of the scattered light intensity. The micro - processor calculates the equivalent particle size of the particulate matter and the number of particulate matters of different particle sizes per unit volume according to the Mie theory.

Technical Parameters:

• Measurable Particle Size Range: 0.3 - 10μm
• Output Interface: It can provide a variety of digital output interfaces.
• Self - calibration Function: It has a power - on self - calibration function.
• Operating Temperature Range: Usually suitable for working in the environment of 0 - 50℃ (the specific value may vary depending on the product model, and this is for reference only).
• Power Supply Voltage: Generally DC 5V (the specific value may vary depending on the product model, and this is for reference only).
• Product Dimensions: The volume is small, which is convenient for integration, and the specific dimensions are subject to the actual product, generally about dozens of cubic centimeters.

Application Scenarios:

It is suitable for a variety of equipment, such as air purifiers, fresh - air systems, air quality monitoring equipment, air conditioners, and portable instruments, and is used to monitor the particulate matter concentration in the air.
