Joy-it Fine dust sensor, I2C, HM3301, 3.3/5V

The HM3301 sensor measures the concentration of fine dust particles in the air using the light scattering method, starting from a particle size of 0.3 μm. With this sensor, you can provide real-time measurements as well as perform continuous measurements, which can then be sent to the connected microcontroller via the I2C interface. It can operate at 3.3 V and 5.5 V, making it ideal for integration due to its architecture. Further technical details and exact specifications can be found in the datasheet in the download area.
