Joy-iT Fine Dust Sensor for measuring the concentration of particles in the air

The HM3301 sensor uses the scattered light method to determine the concent-ration of fine dust particles in the air from a particle size of 0.3 μm. With this sensor you are able to perform real-time & continuous measurements and then send them via the I2C interface to the connected microcontroller.
