Monitor air pollution cheaply and accurately with this matchbox-sized particulate matter (PM) sensor (PMS5003) from Plantower! It senses particulates of various sizes (PM1, PM2.5, PM10) from sources like smoke, dust, pollen, metal and organic particles, and more.

Pair this particulate matter sensor with the and build your own air quality monitoring station to contribute to citizen science projects such as . Just plug the cable into the sensor and then into the connector on the underside of Enviro , and away you go!

The sensor features a small fan which pulls air past a laser. The laser can detect both the size and number of particles in the air. It is important to note that there is a blue protective film that covers the metal casing of the sensor, peel this off before use.

There are two options for digital output: passive and active. The default mode is active after power-up. In this mode, the sensor automatically sends serial data to the host. The active mode is divided into two sub-modes: stable mode and fast mode. If the concentration change is small the sensor would run at stable mode with the real interval of 2.3s. And if the change is big the sensor would be changed to fast mode automatically with an interval of 200~800ms, the higher the concentration, the shorter the interval.

Software: If you are using this sensor with Raspberry Pi, then you'll need to make a couple of changes to its configuration.

• Type (or copy/paste) and enter
  sudo raspi-config
  into the terminal to open the configuration tool.
• Using the arrows navigate down to and select option 3 Interface Options.
• Using the arrows again select P6 Serial Port and answer the questions to disable the login shell (answer No) and enable the serial port hardware (answer Yes).
• Accept your changes and then Finish and close.
• Open a terminal window then type (or copy/paste) and enter
  sudo nano /boot/config.txt
  and add the lines
  enable_uart=1
  and
  dtoverlay=pi3-miniuart-bt
  to the bottom of the file.
• To exit the editor, press Ctrl X together, and then Y then Enter.
• If you are using it with the  board, then the will do all of this configuration for you.

You can also use this sensor with Raspberry Pi Pico (and other RP2040 boards) using this . You can install it easily using 'Tools' > 'Manage Packages' (search for 'pms5003-micropython').

Note:
