The PMS 3003 Sensor

The PMS 3003 Sensor is the third generation evolution of the PMS1003 developped by plantower (chinese name: 攀藤 (pānténg).

Specifications

This is the specification for the PMS3003. One should not consider all those values for granted as there is quite often a big difference between what is said to be possible and what is actually possible (and this is why we are setting up all our experiments).
  • Parameters :Index  (Unit )
  • Measuring range :0.3 to 1.0 ; 1.0 to 2.5 ; 2.5 to 10  (mm)
  • Counting efficiency :50%@0.3um 98% @> = 0.5 um 
  • Response time :≤ 10  sec
  • DC supply voltage :5 V
  • Operating current :120  mA
  • Standby Current :≤ 200  µA
  • Data interface level :L <0.8 @ 3.3 H> 2.7@3.3  V
  • Operating temperature range :-20 ~ + 50  °C
  • Operating humidity range :0 to 99% 
  • MTBF :≥ 3  Year
  • Size :65 × 42 × 23  mm

Inside look at the sensor

Compared to the PMS1003, the PMS3003 is just a mechanical size reduction - the electronic is the same. In the former mechanisms, there used to be a mechanical air chamber, which is now removed a replaced by a simple hole over the diode. This is probably because their attempt to imitate Dylos' pressure drop patent proved to be inefficient in the first generation.
The electronic components are the same, at least for the main CPU, a Cypress CY8C4245. That's a bit disapointing since a higher frequency CPU/ADC could help for the advanced processing so much needed for better understand the air quality. Hopefully this is something we will find in the 7th generation sensor, which is comming quite soon. Stay tunned!
Playing arround with this sensor is quite simple as it exports a serial interface. The pin-out in the following:
  • PIN1  :VCC :Power Supply (5V).
  • PIN2  :GND :Ground.
  • PIN3  :SET :Standby mode (when 0), operating mode (when 1)
  • PIN4  :RXD :Serial receive / TTL level @ 3.3V.
  • PIN5  :TXD :Serial transmit / TTL level @ 3.3V.
  • PIN6  :RESET :Module reset / TTL level @ 3.3V.
  • PIN7,8 :NC :Not connected.

Real-time data

There are two co-located PMS3003 sensors (both are outside). First PMS 3003 outdoor readings are:
  • PM1 count: -,
  • PM2.5 count: -,
  • PM10 count: -,
  • updated on - - (China time).
Second PMS 3003 outdoor readings are:
  • PM1 count: -,

O kvaliteti zraka i mjerenju onečišćenja:

O razinama kvalitete zraka

- Vrijednosti indeksa kvalitete zraka (AQI).Razine zdravstvene zabrinutosti
0 - 50 Dobro Kvaliteta zraka smatra se zadovoljavajućom, a onečišćenje zraka predstavlja mali ili nikakav rizik
51 -100 umjeren Kvaliteta zraka je prihvatljiva; ali ipak, neki zagađivači mogu prouzrokovati umjerenu zabrinutost za zdravlje vrlo malog broja ljudi koji su neobično osjetljivi na onečišćenje zraka.
101-150 Nezdravo za osjetljive skupine Članovi osjetljivih skupina mogu imati posljedice na zdravlje. Vjerovatno neće imati utjecaja na širu popilaciju.
151-200 nezdrav Svatko može početi osjećati zdravstvene posljedice; članovi osjetljivih skupina mogu imati ozbiljnije zdravstvene posljedice
201-300 Vrlo nezdravo Zdravstvena upozorenja o izvanrednim okolnostima. Veća je vjerojatnost da će cijela populacija biti pogođena.
300+ Opasan Upozorenje o zdravlju: svatko može imati ozbiljnije zdravstvene posljedice
