I. Product Name: LUFTMY Infrared PM2.5 Dust Sensor Module

II. Product Model: GDS06

The Infrared PM2.5 Dust Sensor Module GDS06 utilizes the principle of optical scattering to obtain the particulate matter concentration. Since particles and molecules produce light scattering when illuminated, they also absorb part of the incident light energy. The light intensity is proportional to the strength of the photoelectric conversion signal. By measuring the electrical signal, the relative attenuation rate can be obtained, which in turn allows the determination of dust concentration in the test field. PWM and UART communication are then applied via a microcontroller.
