Sensor Characteristics

The output voltage of the module is proportional to dust density in the range of 0 to 0.5mg/m3.

Control principle

  • Enable the internal infrared emitting diode by setting the pin ILED to HIGH.
  • Wait 0.28ms, then the external controller starts to sample the voltage from the pin AOUT of the module. Notes that the output wave will take 0.28ms to reach steady-state after the internal infrared emitting diode is enabled.
