Grove Dust Sensor Air Quality

This Dust Sensor gives a good indication of the air quality in an environment by measuring the dust concentration. The Particulate Matter level (PM level) in the air is measured by counting the Low Pulse Occupancy time (LPO time) in given time unit. LPO time is proportional to PM concentration. This sensor can provide reliable data for air purifier systems; it is responsive to PM of diameter 1μm.

With tweaking, you can also separate out particles 2.5uM and above.

Use the Pi2Grover board to connect to the Raspberry Pi

Warnings

  • This sensor uses a counting method to measure dust concentration, not using a weighing method, and the unit is pcs/L or pcs/0.01cf.
  • Please keep it upright.
  • 3 min preheat time is required while using for the first time.
  • Arbitrary operation may cause unexpected damage.
  • The adjustments on the board (potentiometers) are used only for the factory setting. DO NOT change the default configuration.
