The PMS 3003 Sensor

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

规格

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

看看传感器的内部

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.

实时数据

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

关于空气质量与空气污染指数

本网站采用的污染指数和颜色与EPA是完全相同的。 EPA的指数可以从 AirNow上查到

空气质量指数 空气质量指数级别（状况）及表示颜色 对健康影响情况 建议采取的措施
0 - 50 一级（优） 空气质量令人满意，基本无空气污染 各类人群可正常活动
51 -100 二级（良） 空气质量可接受，但某些污染物可能对极少数异常敏感人群健康有较弱影响 极少数异常敏感人群应减少户外活动
101-150 三级（轻度污染） 易感人群症状有轻度加剧，健康人群出现刺激症状 儿童、老年人及心脏病、呼吸系统疾病患者应减少长时间、高强度的户外锻炼
151-200 四级（中度污染） 进一步加剧易感人群症状，可能对健康人群心脏、呼吸系统有影响 儿童、老年人及心脏病、呼吸系统疾病患者避免长时间、高强度的户外锻炼，一般人群适量减少户外运动
201-300 五级（重度污染） 心脏病和肺病患者症状显著加剧，运动耐受力降低，健康人群普遍出现症状 儿童、老年人及心脏病、肺病患者应停留在室内，停止户外运动，一般人群减少户外运动
300+ 六级（严重污染） 健康人群运动耐受力降低，有明显强烈症状，提前出现某些疾病 儿童、老年人和病人应停留在室内，避免体力消耗，一般人群避免户外活动
