Dust / air sensor SPS30 PM1.0 / PM2.5 / PM4 / PM10 - SPS30 - UART/I2C - SparkFun SEN-15103

Product description: Dust / air purity sensor PM1.0 / PM2.5 / PM4 / PM10 - SPS30 - UART/I2C

The dust sensor allows monitoring of air purity and allows measurement of PM1.0, PM2.5, PM4 and PM10 particles.It is equipped with a high quality optical sensor that uses laser scattering and innovative dirt immunity technology. The sensor can detect particles with a diameter of more than0.3μm, such as cigarette smoke. It is powered from 4.5 V to 5.5 V. It communicates via UART or I2C.
