PMS9103M Laser - Based Dust Particle Sensor For Indoor Air Quality Monitoring

                       PMS9103M Laser - Based Dust Particle Sensor For Indoor Air Quality Monitoring

The PMS9103M is a digital universal dust particle sensor module that adopts the laser scattering principle. It is capable of continuously collecting and calculating the number of suspended particles of different sizes in the air per unit volume, converting the data into mass concentration, and outputting it through a standard digital interface. The sensor comes with a six - sided all - round shielding structure and an ultra - thin design with a thickness of only 12mm, which not only enhances anti - interference ability but also makes it easy to be embedded into portable devices. It is commonly used in air purifiers, fresh air systems, air quality detectors and other equipment to provide real - time and accurate particle concentration data.

Features:

• Precise and stable detection: By relying on the laser scattering principle and Mie theory algorithm, it can accurately identify particles as small as 0.3μm, and the data consistency is excellent with an error not exceeding ±10%.
• Strong anti - interference capability: The six - sided all - round metal shielding structure effectively reduces the interference of external electrical signals and electromagnetic fields, ensuring stable data output in complex environments.
• Flexible working modes: It supports normal working and sleep modes, which can be switched through the SET pin. This helps reduce power consumption when the sensor is not in use, being suitable for battery - powered devices.
• Easy integration: The ultra - thin size and standard UART digital interface facilitate quick connection with microcontrollers such as Arduino and Raspberry Pi, significantly shortening the secondary development cycle of terminal products.
