SEN-HM3301 Arduino - Fine dust sensor, HM3301

The HM3301 sensor determines the fine dust particle concentration in the air using the scattered light method from a particle size of 0.3 µm.

With this sensor you are able to provide real-time readings as well as continuous measurements and then send them via the I2C interface to the connected microcontroller.
