The SPS30 is an optical particulate matter concentration sensor, similar in principle to SDS011, but offering much better accuracy. First, it returns data not only in µg / m3 concentration, but also the measured number of particles of a given size.

Why is it so important? Each dust is different, depending on what source it comes from. So it is obvious that the mass of particles from different sources can be different, despite the same size. The optical sensor measures dust by counting particles of a given size, not weighing them. In order to give a result in units of mass per volume, the sensor has to assume some constant parameter, thanks to which it can convert the number of particles to mass. SPS30, also giving the number of particles, allows you to make your own calculations, if you have some information about the type of pollution.

The SPS30 sensor is also more accurate, categorizing dust according to the size categories PM1, PM2.5, PM4 and PM10. From the smog point of view, it is very important to distinguish PM1. The smallest particles enter our bloodstream most easily. Larger ones (especially those above 2.5 µm and closer to 10 µm) are caught by our respiratory system.

The elements of the SPS30 ventilation system as well as the laser system allow for many years (about 5-8) of continuous operation.

The SPS30 is supported by the latest NAM firmware, but at the moment (June 2020) we have not yet developed a procedure to properly mount the SPS30 inside the NAM housing.


The sensor has a JST ZHR-5 connector, there is no connection cable. If you want to connect it to NAM or other µc, you will also need:

  • connector ZHR-5
  • 5 wires - 5V, GND, SDA i SCL. Pin 4 on connector (verify orientation in datsheet SPS30) should be connected to GND - it forces I2C mode, which is used by NAMF to connect to SPS30

Set includes:

  • SPS30 sensor (connection cable not included)
