New version Smart Citizen Kit available | Waag

Posted by jpluimers on 2021/07/05

By now it should be able to order them normally, as this link is from early 2019: [WayBack] New version Smart Citizen Kit available | Waag

An improved 2.1 version of the Smart Citizen Kit is now ready for pre-ordering.

What does the 2.1 version measure?

The Smart Citizen Kit focuses on the weather, sound, light and air quality. The following overview shows the different sensors in version 2.1:

  • Temperature (°C) – Sensirion SHT31
  • Relative humidity (% rh) – Sensirion SHT31
  • Noise level (dBA) – Invensense ICS4342
  • Ambient light (lx) – Rohm BH1721FVC
  • Air pressure (barometer, kPa) – NXP MPL3115A2
  • Equivalent carbon dioxide (CO2 in ppm) – AMS CCS811
  • Volatile organic compounds (ppb) – AMS CCS811
  • Particulate matter (PM1/2,5/10 in μg/m3) – Plantower PMS 5003

Our findings in 2014 showed that the housing can be an important factor by influencing the sensors; there must be sufficient air flow, but also a watertight environment. And the placement is important (not in full sun for example).
