This optical dust sensor can measure the air quality very accurately by measuring air particles or dust based on laser detection.
This sensor is supplied with the accompanying cable and USB to serial converter to connect the sensor to a computer if needed.


  • Voltage: 4.7 - 5.3V DC (5V DC with <20mV ripple advised)
  • Power consumption: 70mA ±10mA (in operation), <4mA (laser and fan sleep mode)
  • Measuring range: 0.0-999.9 μg/m3
  • PM2.5 and PM10 output
  • Lifetime laser diode: up to 8000 hours (with continuous operation*)

* For example, measure every 30 seconds or every 5 minutes to extend the life span.

Pinout of the connector:

Pin NameDescription

For more information see the datasheet and UART protocol under the tab "Downloads and Links".

The drivers for the USB serial converter can be found here:

Note: users report that the driver for Mac can be unstable on both old and new computers, read  this extra link   to get it working.

For examples of this sensor in combination with an Arduino see: Using SDS011 Dust Sensor and Instructies voor het samenbouwen van een eigen fijnstof sensor
The RIVM tested this sensor and is being used for air quality measurements: Sensoren voor fijn stof (PM2,5/PM10)
