APM10 is a digital particulate matter detection sensor designed based on the laser scattering principle, also known as a PM2.5 sensor. Here is the relevant English - language information:

Product Features:

• High - precision Detection: It can detect ultrafine particulate matter as small as 0.3μm. By using professional algorithms and calibration detection processes, its detection ability for ultrafine particulate matter has been greatly enhanced. It adopts dual - frequency data collection technology, which can achieve real - time response and support continuous collection.
• Good Stability: With laser self - calibration technology, it has good stability and consistency, which can provide reliable information for users.
• Strong Anti - interference Ability: It adopts a full - metal shielding shell, which has strong anti - interference ability, and can ensure the accuracy of detection results in a complex electromagnetic environment.
• Small Size and Easy Integration: The product size is only 49×31.5×10.8mm, with ultra - thin packaging, which is convenient to be integrated into various indoor air quality monitoring equipment, such as air purifiers, air fresheners, ventilation equipment, and in - car air purifiers.
• Standard Output Interface: It adopts a standard I2C digital output signal, which is convenient for connection and communication with other devices.

Working Principle:

APM10 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.

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.
