The DSM501A dust sensor module is a compact, low-cost solution for particle density measurement.
Overview
The DSM501A is a compact, low-cost particulate matter sensor designed to measure air quality by detecting fine dust particles. It operates on the principle of light scattering, providing a PWM output signal proportional to the concentration of particles in the air.
This module integrates an infrared LED, a photodetector, and an internal heating element that facilitates automatic air intake without the need for an external fan. It features one control pin and two output pins, making it straightforward to interface with microcontrollers like Arduino or Raspberry Pi.
