Samyoung Optical Dust Sensor DSM501A RPIACC only an IO port toThis optical dust sensor can measure the air quality by measuring on air particles dust. The Air Quality Index (IAQ) is fairly easy to determine using an Arduino (or ESP32, ESP8266) and a DSM501 sensor. The DSM501A is a detector capable of measuring the presence of fine particles in suspension in the atmosphere according to PM2. 5 and PM10 standards. The DSM501A is a very economical sensor which can be used as a base to build an air quality
