Description

Monitor air pollution cheaply and accurately with this matchbox-sized PMSA003?particulate matter (PM) sensor from Plantower! It senses particulates of various sizes (PM1, PM2.5, PM10) from sources like smoke, dust, pollen, metal and organic particles and more.

The sensor has a small fan that sucks air through the sensor and past a laser that can detect both the number (and hence concentration) and size of particles in the surrounding air.

The sensor comes with an adapter board, allowing you to hook it up to a microcontroller with standard jumper wires using VCC/GND/RX/TX.

Here’s an example of a similar sensor in the range (pin-compatible so should work the same) hooked up to a Raspberry Pi Zero using just VCC/GND/RX/TX.

PMS5003 vs PMS7003 vs PMSA003

We stock three different models of particulate sensor from Plantower, so the first question you might have is?“What’s the difference between the PMS5003, the PMS7003 and the PMSA003?”.

There’s a slight difference in price between the models, and from a technical perspective, here are the differences from Plantower’s website -?there’s not a lot in it – physical size being the main difference along with slight differences in current usage:

Connection differences

• The PMS5003‘s connector is a Molex Picoblade i.e. a direct connection to the included wire.
  • This can be used with one of our adapter boards to break all six pins out to 2.54mm jumper wires.
• The PMS7003 and PMSA003 have small 2×5 block connectors which their included adapter board slots into.
  • This included adapter board only offers VCC/GND/RX/TX on the 2.54mm breakout (fine for Pi projects) and does not break out the SET or RST pins (unless you use the Picoblade header).

Release date

The sensors reduced in size each release, however, as per the table above, technically there’s very little difference between them. In order of old to new:

• • PMS5003
  • PMS7003
  • PMSA003

Features

• Plantower PMSA003 Particulate Matter (PM) Sensor (manufacturer link)
• Detects PM1, PM2.5, PM10 particulates
• Included adapter board
• UART serial interface
• Dimensions: 38mm??35mm??12mm

Note: There may be a blue protective film that covers the metal casing of the sensor, you can peel this off before use if so.
