DSM501A Dust Sensor (PM2.5 / PM10)

Overview:
The DSM501A is an optical dust sensor designed to measure the concentration of airborne particles by detecting light scattered from dust passing through its sensing chamber. It provides a digital pulse output that correlates with particle density, making it suitable for basic PM2.5 and PM10 monitoring in embedded and DIY systems.
